Product list Resistance-dependent measurements
TERMITRAB complete provides protection against surge voltages for resistance-dependent measurements, such as Pt 100 temperature measurements.
In the case of resistance-dependent measurements, the internal resistance of the surge protective devices can cause an unwanted change to the measurement result. For this reason, protective circuits with an extremely low self-impedance are available for these applications.
Your advantages
- Space-saving installation with the narrowest protective devices
- Versatile use: designs and connection technology adapted to the application
- Easy testing, thanks to pluggable version of surge protective devices
- Worldwide use in potentially explosive areas, thanks to ATEX and IECEx approvals
Resistance-dependent measurements
If a measured variable is determined directly based on the resistance value of an electrical component, the additional impedances within the measuring loop play a special role. This affects, for example, temperature measurements with platinum resistance detectors (Pt 100, Pt 1000) as well as strain gauges with two-wire technology. As a rule, MCR surge protection products contain impedances in the common mode paths. If the impedances are introduced into the circuit without recalibration, the measurement result will be falsified due to the change in the total impedance. Circuit versions without additional longitudinal resistances simplify the installation of surge protection in applications of this kind.

TERMITRAB complete: multi-stage, one-piece, without signaling
One-piece, multi-stage surge protective devices without status indicator for nominal voltages of up to 24 V DC are available for a range of circuit versions. They are available with Push-in or screw connection.
PLUGTRAB PT
With an overall width of 17.5 mm, PLUGTRAB PT is a range of pluggable surge protective devices for a variety of voltage and circuit versions. The protective plugs are tested with the CHECKMASTER 2. The PLUGTRAB PT product range is available with screw connection technology.
LINETRAB
The LINETRAB product range provides surge protection on an overall width of 6.2 mm. This allows you to protect up to four signal wires for digital or analog interfaces, including in intrinsically safe areas. Multi-conductor temperature measurements can also be performed via an optional DIN rail connector. LINETRAB is available with screw connection technology.
SURGETRAB S-PT
The SURGETRAB surge protective devices can be screwed directly onto field devices such as measuring elements. Product versions for parallel and through wiring are available. Various voltage and circuit versions are available with different connecting threads. SURGETRAB is available for Ex areas with type of protection Ex i (intrinsically safe) and Ex d (pressure-tight encapsulated).
