Temperature sensors for test benches and automotive
Temperature measurement on the test bench and in vehicle testing makes different demands from process engineering: the measuring point sits on a moving or hard-to-reach component, the temperature jumps within seconds, and the sensor has to withstand vibration, brake dust and brake fluid.
For these cases we make five designs: two sliding thermocouples for the brake disc, a plug-in and drive-in sensor for the pad and the component, a screw-in sensor for the brake fluid and a black-standard thermometer for weathering tests. The four proven designs have been in use in brake test benches and test vehicles for decades; the TAM-4 adds a spring clip for road testing.
We manufacture in Hanau to your specification — lengths, cables, connectors and threads freely selectable, single pieces and rebuilds to sample or drawing included.
Which sensor suits your measuring point?
| What is measured | Typ | Measuring principle | Limit |
|---|---|---|---|
| Brake disc while running | TAM-1 | sliding, spring-loaded measuring point | bis +1.000 °C |
| Brake disc in road testing | TAM-4 | spring clip with sheathed measuring tip Ø 0.5 mm, contact pressure adjustable | bis +800 °C |
| Brake pad, caliper, component | TAM-2 | tip plugged, driven or caulked in | bis +1.000 °C |
| Brake fluid in the system | TAM-3 | screw-in sensor with a 90° sealing cone | 320 bar · +300 °C |
| Surface under radiation | WSS | black absorber plate with Pt100 | 0…+200 °C |
All thermocouples are type K (the TAM-3 also type N), the measuring junction either grounded or isolated. Connection as a free end or a mini thermocouple plug in IEC green or ANSI yellow.
Choose a design and configure it
Five designs, each with a dimension drawing, technical data and the order key as a configurator. Choose the design that suits your measuring point.

Brake disc
TAM-1
Sliding measuring point on the rotating disc — spring-loaded, grounded.
Ø 7,9 mm · LF 15 / 26 mm · bis +1.000 °C

Brake disc · road testing
TAM-4
A spring clip presses a sheathed measuring tip Ø 0.5 mm onto the disc — contact pressure adjustable, bracket for screwing on.
Ø 0.5 mm · sensor part 80 mm · up to +800 °C

Brake pad & component
TAM-2
Short metal tip for plugging, driving or caulking in — very short response time.
tip Ø 2 / 3 mm · up to +1,000 °C

Brake fluid
TAM-3
Screw-in sensor with a 90° sealing cone, measures directly in the hydraulic system.
15 threads · up to 320 bar · up to +300 °C

Weathering
WSS
Black-standard thermometer to ISO 4892-1 — surface temperature under radiation.
Pt100 4-wire cl. A · 0…+200 °C
Connection and cable
Thermocouple plugs
Mini thermocouple plugs come in the standardised colour: green to IEC 60584-3 and yellow to ANSI. Both variants can be chosen for the TAM-1, TAM-2 and TAM-3, as can the plain cut free end for your own wiring.
Cable
FEP with a Cu braid is the standard cable on the test bench, glass fibre withstands up to 600 °C, silicone is particularly flexible. The operating temperature in the order keys applies to the measuring point — the cable has to lie outside the hot zone or be selected accordingly.
Sheathed thermocouples and sheathed resistance thermometers for general test-bench use can be found under Sheathed thermocouples und Mineral-insulated resistance thermometers.
