THERMOSTATS
Trafag thermostats are available for the following tasks:
- monitoring of room temperature in many different areas of application
- monitoring of room temperature in many different areas of application
The temperature sensors can by choice be supplied fitted directly on the housing or apart.

Operating temperature (°C):
Ambient temperature at which the device may be operated:
-30...50/-30...70 /-30...85 /-15...70
Sensor types
The capillary tube sensors differ in method of connection:
- Sensor fixed directly at the housing
- Sensor remote from the device (e.g. at very high measurement temperatures, or for remote positioning of sensor and device due to separate disposition of measurement signal loop and measuring point)

Protection against breakage of capillary tube (option)
Protection against breakage of a capillary tube is an element of safety. Should the capillary tube break or leak, the micro switch switches to off as if the set limit temperature had been reached.
Types of housing
- Polymer: For protected indoor use
- Metal: For industrial in- or outdoor use under harsh conditions
Micro-switch versions
- Different switching capacities
- Varied differential gaps (fixed value or adjustable)
- Gold-plated switching contacts for Ex applications
- Versions for added stability against vibrations
- Types with 1 or 2 micro switches (partly with adjustable intervals)
Micro switch reset (option)
The thermostats can be supplied optionally with a reset button. After switching of the micro switch, the switch maintains this condition until it is manually reset. This can be important in the case of safety-relevant applications (e.g. overheating protection). Depending upon device model, the reset button is situated as follows:
- inside the device (housing must first be removed to gain access to the button)
- outside the device (direct access to the button from outside the device)
IP protection ratings
- IP54
- IP65
Switchpoint settings
To set the switchpoint, there are two possibilities:
- via adjusting screw (adjustment by screwdriver)
- via adjusting knob (adjustment by hand)
The switchpoint is adjusted according to a scale. Depending on device model, the adjustment knob is situated as follows:
- inside the device (housing must first be removed to gain access to the knob)
- outside the device (direct access to the knob from outside the device)
For standard products, the switchpoint is set by the user. On request, Trafag carries out setting of the switchpoint in line with the specifications of the customer. In a such case, the devices can be supplied complete with calibration certificate upon request.
