Honeywell – R1/MS STW / STB Safety strap-on thermostats

STW / STB Safety strap-on thermostats are used in self- monitoring sensor systems for temperature monitoring and limiting tasks, e.g., for floor-heating applications.If the sensor is damaged, i.e., if the expansion fluid in the capillary tube leaks, the strap-on thermostat responds as though the temperature has exceeded the set-point and will thus switch to the safety setting (e.g., will switch off the circulation pump).To ensure reliable functioning, the surface of thepipe must be thoroughly cleaned of contamination, rust, paint, etc. Each thermostat is delivered together with a strap allowing attachment to pipes having a diameter of up to 100 mm. Additionally, the thermostat can be mounted to walls using the capillary. An optional immersion well allows use as an immersion sensor. This demonstrates the great versatility of this innovative device, which is also reflected in the small quantity of stock kept on hand by customers. Among the innovative features of this device are its automatic temperature compensation and the Push-In® contacts for quick wiring. The devices are CE-approved and certified according to Pressure Equipment Directive DIN EN14597.
