Products

We are specialists in position sensing, in other words feed back signal from a linear or rotary sensor. With our experience we will guide you to the best solution, no matter if you need some standard components from our stock or larger quantities of a customized sensor.

Process sensor / Ship-approved / Ship-approved thermostats

Ship-approved thermostats

Mechanical Trafag 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
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
