STW II Capillary Tube Thermostat 16 A Fail-Safe

The STW II is a compact ON/OFF type capillary tube thermostat, housed in an Ex e certified polyester enclosure. Heaters, fans, motors and other equipment are energised and de-energised by means of this thermostat when specific temperature ranges are exceeded. This device can also be used to control the temperature in air or on various surfaces.

FUNCTION

Any change in temperature at the sensor bulb causes a change in the volume of fluid in the measuring system, which in turn results in a movement of the diaphragm membrane. This membrane is connected to a mechanical device that activates a microswitch. If the temperature at the sensor bulb exceeds the pre-set value, terminals 1 and 4 are opened. If there is a rupture or break in the sensor tube (leakage), then the switch remains permanently open (fail-safe). If the temperature falls below the minimum setting, the autocontrol opens the circuit but closes again on temperature rise.

APPLICATION EXAMPLE

The STW II thermostat can directly switch temperature-dependent equipment loads (heaters etc.) of up to 16 A. Higher rated currents can be switched by means of a contactor; the STW II switches the contactor coil. If an interlock is installed by means of an additional relay (according to DIN VDE 0116), the STW II can also be used as a limiter.

FEATURES

• Small construction
• Varying temperature ranges can be combined in one enclosure
• Can be mounted directly in Zone 1
• Temperature can be set in Zone 1
• Many variants available

DTW DTB Flame Proof Temperature Monitor Limiter

The flame-proof encapsulated temperature controllers/limiters (DTW/DTB) are designed for (trace)-heating applications in the Ex area. They can be used both for protection against frost and for maintenance temperature applications. Heating units and other operating equipment are switched on and off by means of the temperature controller when the temperature is too high or too low. The DTB temperature limiter is designed with resetting lockout; resetting (restarting) is only possible on the device. Can be used for monitoring temperature in the air or on surfaces.

FUNCTIONS

A change in temperature in the sensor causes a change in volume in the fluid filled in the measuring system, which in turn results in a movement of a membrane, which is connected to transmission mechanics and activates a microswitch. If the sensor temperature exceeds the pre-set level, the contact is actuated. The temperature limiter switches off permanently if the temperature is exceeded. Once the temperature drops, the temperature limiter can be unlocked manually. If there is a break in the measuring system (leakage), the circuit remains open permanently.

APPLICATİON EXAMPLE

DTW and DTB switch temperature-dependent equipment (heating units) of up to 22/16 A directly. Higher switching currents or 3-phase applications are switched by means of a contactor.

RLAnet Monitoring Unit

• Quick and precise localization of the leakage location

The monitoring unit RLAnet is a component of the BARTEC Water leakage detection system. It is operating with the sensor cable SCR and/or the point sensor PS. Further components of the BARTEC Water leakage detection system are the monitoring units RLW, RDW 03 and RDA 01, also the accessories. The system detects minor liquid leakages fast and reliable. An optical and acoustic signal arises. Simultaneously the potential-free contact switches. This can be used for signalling to PLC or to a building control unit. The leakage is being localized exact by 1 meter and get visualized on the 4-digit display. Thus a leakage will be found by a service person quick and true.
