Robust Mechanical Thermostats for Temperature Control
Mechanical thermostats are used in applications where temperatures are controlled by means of a simple electrical on/off switching signal. These instruments operate failsafe under harsh operating conditions (e.g. extreme fluctuation of ambient temperature) and are insensitive to outside environmental conditions.
Measuring Principle of Thermostats
The medium in a capillary tube reacts to temperature changes on the principle of heat expansion. This expansion is measured by means of a fine mechanical construction which activates one or several micro-switches.
Available Versions
- internal or external temperature adjustment
- measuring scale inside or outside
- with (limiter)/without resetting
- with/without ΔT (switching differential) adjustment
- instruments for inside or outside applications
- optional capillary tube breaking safety device
- One- or two-stage circuit
- CE, EX or ship approval
Sensor Systems/Auxiliary Equipment
- fixed or freely mountable sensor
- sensor material from copper (Cu), Cu nickel plated or stainless steel
- brass nickel plated or stainless steel sensor protection tube
- additional capillary tube protection
