Outside temperature probe with metal head

Delivery in 3 to 5 weeks
Description and application
These resistance temperature sensors are intended for measuring the contact temperature of gaseous substances. The standard temperature range in which the sensors can be used is between -30 ° C and 100 ° C. The sensors can be used for any control system compatible with the output signals of the sensing elements or the output signals shown in the table of sensing element types.

The temperature sensors are designed to operate in a chemically non-aggressive environment.

Before connecting the input cable, unscrew the metal connection head cover. The input cable is then connected to the corresponding terminals in the loose grommet according to the wiring diagram. Recommended wire section: 0,35 to 1,5 mm2, the outer diameter of the circular cable section can be 4 to 8 mm.

If the input cable is laid near high voltage conductors or those supplying equipment creating a disturbing electromagnetic field (e.g. equipment with inductive load), shielded cable should be used. To ensure IP 54 ingress protection, the grommet must be tightened and the cover screwed on after connecting the inlet cable.

The openings for the installation of the stainless steel brackets are drilled according to the dimensional draft, where the hole diameters and the distances between the hole centers can be found.

After installing and connecting the sensor to the appropriate electrical equipment, the sensor is ready for use. The sensor does not require any special servicing or maintenance. The sensors can be placed in any operating position, but the grommet must not be pointing upwards.
