Product features Temperature sensor - plastic connection head

Probe with plastic connection box

DESCRIPTION AND APPLICATION

These resistance temperature sensors are designed to measure the contact temperature of liquid or gaseous substances. The plastic connection head is provided with a cable outlet (the terminal block is placed in the connection head) or a connector.

La combination temperature sensor and central supportIt is suitable for temperature measurements in air conditioning ducts. The combination temperature sensor and thermowells suitable for temperature measurements in tubes.

The temperature sensor variant with welded thread is ideal for the direct measurement of fluids in pipes. The standard operating temperature range is between -30°C and 150°C.

By using a sensor with a longer rod, the upper limit of allowable temperature can be extended up to 250°C. Temperature sensors can be used for any compatible control system with the sensing element output signals or the output signals shown in the sensing element type table.

The temperature sensor is easy to mount thanks to the unique design "S-head".

SENSOR INSTALLATION AND MAINTENANCE

WELL DETECTORS:

Before connecting the power cable, pry off the plastic connection head cover using a flat screwdriver. The input cable is connected to the terminals according to the wiring diagram through the loose eyelet. The recommended wire section is 0,35 to 1,5 mm2.

The diameter of the circular section cable can range from 4 to 8 mm. To ensure the protection value IP 65 , the grommet must be tight and the cover must be put on after connecting the input cable.

SENSORS WITH CONNECTOR:

The input cable with connector is connected to the RSFM4 connector, which is part of the sensor head. Optionally the autonomous CONEC connector 43-00092, or an input cable with a length of 5 m equipped with a straight RKT connector, or a rectangular type RKWT connector can be delivered.

To guarantee the protection value IP 65, the connectors and the sensor cover must be tightened and checked. If the input cable is laid near high voltage conductors or those supplying equipment creating a disturbing electromagnetic field (eg equipment with an inductive load), shielded cable must be used.

When using a stainless steel thermowell or stainless steel bracketthese
accessories should be placed first where the temperature will be measured. Then the sensor is inserted into the holder or pushed as far down the thermowell, and tightened with a screw.

Openings for the installation of the plastic clamp must be drilled in accordance with the dimensions sketch on which the opening diameters and the distances from their centers are illustrated.

After installing and connecting the sensor to the equipment, the sensor is ready for use. The sensor does not require any special servicing or maintenance. The device can be used in any working position, but the eyelet must not be pointing upwards.
