Probe with seamless plastic connection box

Temperature sensor - plastic connection head *Step required

In production :  2 to 3 weeks

Description and application
These resistance temperature sensors are designed to measure the contact temperature of liquid or gaseous substances. The plastic connection head has a cable outlet (the terminal block is placed in the connection head) or a connector. The combination of temperature sensor and central support is suitable for temperature measurements in air conditioning ducts. The combination of temperature sensor and thermowell is suitable for temperature measurements in tubes. The temperature probe variant with welded thread is ideal for direct measurement of fluids in ducts. The standard operating temperature range is between -30 ° C and 150 ° C. By using a sensor with a longer rod, the upper allowable temperature limit can be extended up to 250 ° C. The temperature 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 sensor is easy to mount thanks to the unique "S-head" design.

SENSOR INSTALLATION AND MAINTENANCE

WELL DETECTORS:
Before connecting the power cable, lift the cover of the plastic connection head 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 IP 65 protection value, 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 CONEC 43-00092 standalone connector, or a 5 m long input cable fitted with a straight RKT connector, or a rectangular type RKWT connector can be delivered. To guarantee the IP 65 protection value, 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 which creates a disturbing electromagnetic field (for example, equipment with inductive load), a screened cable must be used. When using a stainless steel thermowell or stainless steel support, these
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. The openings for the installation of the plastic clamp must be drilled in accordance with the sketch dimensions on which the opening diameters and the distances from their centers are illustrated.
After installing and connecting the sensor to the sequential evaluation electrical equipment, the sensor is ready to use. The sensor requires no maintenance or special maintenance. The device can be used in any working position, but the eyelet must not point upwards.

MODIFICATION AND CUSTOMIZATION
FOR THE STANDARD DETECTORS MANUFACTURED, THE FOLLOWING PARAMETERS CAN BE MODIFIED:
- possibility of coating two sensitive elements
