EX PROOF HEAT TRACING EQUIPMENT

BSTW II Safety Temperature Monitor And BTB II BSTB II Limiter 25 A Fail-Safe

BSTW II temperature monitors and BTB II/BSTB II temperature limiters are ON/OFF thermostats in Ex e certified polyester enclosures. In addition to the use of conventional power cables, BSTW II and BTB II/BSTW II are approved for the direct connection of self-limiting BARTEC heating circuits in the enclosure terminals. A verification of thermal safety and a further approval by any third party authority is not necessary. The benefit to the customer is obvious. Any directly connected self-limiting heating circuit considerably reduces the number of junction boxes and installation cost. BSTW II and BTB II/BSTB II monitor ambient temperatures as well as different surface temperatures. In accordance with EN 60079-30-1, BTB II and BSTB II fail-safe temperature limiters are designed to switch off and remain switched off when the preset limit temperature is reached. The restart lockout requires manual resetting directly at the device.

Application Areas:

• Industrial furnaces
• Heating systems
• Plastic processing machines
• Food processing equipment
• Chemical processes
• Laboratory equipment
• Power plants
• HVAC systems
• Extruder Heating
• Hot press applications.

FUNCTION

Any change in temperature in the sensor causes a change in the volume in the liquid-filled measuring system, which in turn results in a movement of the diaphragm membrane, which is connected to a transmission mechanism, and this opens a microswitch. If the sensor temperature exceeds the set value, the contacts 1 and 2 remain continuously open. The contacts in the BTB II/BSTB II remain continuously open until there is a manual intervention.

FEATURES

• Direct connection of self-limiting heating tapes by means of BARTEC’s cold-applied technology reduces wiring and materials
• Switching voltage up to 400 V and 2 M20 x 1.5 boreholes as standard for an enhanced operation of EKL heating circuits
• Safety cut-out temperature -45 °C or -55 °C for reliable operation, even in very cold conditions
• Minimum operating temperature -55 °C for all standard variants for use all over the world without restrictions
• Wide regulating range from -20 °C to +500 °C, depending on the switch insert

BSTW II

Fail-safe safety temperature monitor.

• Falling calibration to maintain the temperature during the process
• Turns on and off automatically whenever the temperature exceeds or drops below the setpoint value

BTB II

Fail-safe temperature limiter.

• Rising calibration to limit temperature during the process
• Switches off and remains switched off once the limit temperatures are reached

BSTB II

Fail-safe safety temperature limiter.

• The BSTB II functions in the same manner as the BTB II temperature limiter, whereby the setting range is limited here to 0 °C to 130 °C or 130 °C to 190 °C based on the temperature classes T3 and T4.

Pt100 M Resistance Thermometer

• Fast response time
• Flexible connection cable for easy installation
• Compact dimensions, compact design

This Pt100 Ex sheathed resistance thermometer has been particularly designed for use in potentially explosive areas. As it meets the requirements of the Ex m type of protection, intrinsically safe circuits can be dispensed with. Thanks to the pliable part of the resistance thermometer, the device is excellently suitable for application areas requiring a high degree of flexibility and replaceability (e.g. chemical and power plants)

Structure The resistance thermometer is made of a 3 mm mineral insulated cable with different lengths. This light mineral insulated cable is filled with magnesium oxide. The pliable part of the resistance thermometer starts after 50 mm. Via a transition gland, the connection to a flexible supply cable is created.

Function Metals increase the electrical resistance with rising temperatures. The platinum element of the resistance thermometer has a resistance of 100 Ω at 0 °C. This characteristic is used for this type of resistance thermometers to get an image of the temperature. The resistance changes of the Pt100 Ex are converted into a temperature value and displayed by a control unit.

Application Areas:

• Industrial furnaces and dryers
• Chemical processes
• Food processing
• Pharmaceutical production
• Power plants
• HVAC systems
• Laboratories
• Plastic processing machines
• Metal processing
• Automotive industry
• Greenhouse and agricultural applications
• Extruder Heating
• Hot press applications.

DTL III Ex Digital Safety Temperature Limiter

• ATEX approved limite
• Optimised for trace heating applications (with service contact
• In conjunction with Pt100 Ex, it can be used for monitoring temperature in explosionprotected heating circuit

The DTL III Ex digital temperature limiter, which is adapted to (trace) heating applications, serves to monitor heating and heating circuits. The device is installed in the non-hazardous area. The heating or heating circuits can be installed both in media-protected and also in hazardous areas. Thanks to their integrated power supply unit with wide-range voltage, the devices can be used almost everywhere in the world

Function If the temperature at the Pt100 exceeds the set limit value, the DTL III Ex permanently interrupts the normally closed 16 A switch contact. This situation is detected by a volt-free alarm contact (change-over contact) and passes on the signal to the control panel. After a temperature drop of 5 K below the limit set point, or after a fault has been remedied, the limiter can be re-activated by means of a re-set button on the device itself or via a remote re-set control. The DTL will also interrupt the switch contact in the event of a sensor open or short circuit. Process reliability is increased by additional monitoring functions such as supply voltage monitoring, pre-alarm, measuring circuit monitoring for sensor break, interruption and short-circuit as well as undershooting/overshooting of the measuring range. A multi-stage password management is available for effective parameter protection. When doing service work on the heating circuit, the load output can be turned off by means of a digital input and the temperature alarms can be disabled. Using the programming interface, the device parameters can be read out with a programming key and transmitted to other devices.

Structure The DTL III Ex is integrated in a latch-on enclosure for TS 35 mounting rails. The alarm relay is produced as a change-over contact and the limit relay as a normally open contact. The voltage is supplied to the control device through an integrated power supply unit with wide-range voltage. The electrical connection is established with terminal screws operating on the screw cage clamp principle, ensuring a safe connection that is gentle on conductors.

Application Areas:

• Oil and gas industry (refineries, platforms)
• Chemical industry (chemical plants)
• Mining
• Paint industry
• Flour and sugar factories
• High temperature furnaces (in hazardous areas)
• Heat treatment plants (in hazardous areas)
• Hazardous material storage
• Extruder Heating (in hazardous areas)
• Hot press applications (in hazardous areas)
• Heating cable applications (in hazardous areas)
• Sensor connections (in hazardous areas)

DPC CodeKey Programming Key For DPC III And DPC

• Easy programming of DPC devices
• Operation independent of voltage supply
• SMART converter function USB/RS485

The DPC CodeKey makes it easier to set parameters for the DPC device family. Once a reference device has been successfully programmed, the operating parameters are available in a device-memory read-out. The parameters filed in the CodeKey can be copied into other devices any number of times. This reduces the programming work to a minimum. In addition, the CodeKey can be used as an interface converter between the USB and RS485.

Mode of Operation A DIP switch can be used to select the device function required. The DPCfront and DPC III have at the side or under the display cover a 5-pin interface into which the CodeKey is inserted. The transmission is started at the press of a button. Once done, a status LED flashes. Voltage is supplied to the CodeKey through the interface.

Application Areas:

• Industrial furnaces and drying systems
• Plastic processing machines
• Food processing equipment
• Chemical processes
• Laboratory equipment
• Heat treatment plants
• Power plants
• HVAC systems
• Extruder Heating
• Hot press applications
• Rapid configuration of multiple DPC control devices
• Mass production and calibration in factory environments
• Maintenance and repair of DPC control devices
• Secure storage of programming parameters.
