Description

Thermostats control and monitor thermal processes. Instruments of the ATH series are available as temperature controllers TR, temperature m onitors TW, safety temperature monitors STW (STB), and safety temperature limiters STB. When malfunctions occur, the STB places the sys- tem being monitored in a safe operating status. Surface-mounted thermostats operate according to the fluid expansion principle. A microswitch is used as an electrical switching element. Switching functions Temperature controller TR and Temperature monitor TW If the temperature on the temperature probe exceeds the setpoint value, the electrical circuit is opened or closed by a microswitch. If the temperature falls below the selected setpoint value (by the switching differential), the microswitch is reset to its initial position. Restart lock at safety temperature limiter STB If the temperature at the temperature sensor exc eeds the set limit value, the electrical circuit is opened and the microswitch is mechanically locked. After falling below the limit value by approx. 10 % of the temperature range (approx. 15 % of the limit value setting > +350 °C), the switch can be unlocked manually. Use of the safety temperature monitor STW as safety temperature limiter STB In this case, the circuit following the thermostat must comply with DIN EN 14597 and VDE 0116. Self-monitoring for safety temperature limiter STB and safety temperature monitor STW (STB) If the measuring system is destroyed (i.e. if the expansion fluid escapes ) the pressure in the membrane of the STB and STW (STB) drops and per manently opens the electrical circuit. Un- locking is then no longer possible. When the ST W (STB) and STB sensors cools down to the negative temperature range, the circuit opens, but must be unlocked manually by the reclosing button when the temperature rises. The STW (STB) restarts automatically. 1 Available upon request. ATH-1 (Type 603021/01-1-...)
