This sensor comprises a plastic head and stainless steel tube in which is placed a temperature sensor. In the head is a terminal block or a converter with a terminal block, to which the power cable intended to supply the sensor and to the digital output signal are connected via a cable gland and a connector. 

SD 122,  communication protocol SD 122K MODBUS / RTU, RS485 communication

The temperature range of the sensors is defined in the table of technical parameters for each variant. The sensors comply with the protection class IP 65 in accordance with the modified standard EN 60529. 

The sensors are designed to operate in a chemically non-aggressive environment, the method of use must be chosen according to the temperature and the chemical resistance of the sensor head.

The sensor is manufactured in a variant:Modbus RS485 temperature probe

  • SD 122 - the control structure corresponds to the ModBus RTU communication protocol.

ACCESSORIES

  • central plastic support
  • stainless steel etablowmowell JS 130
  • central metal support
  • screw with collar or cutting rings - if different immersion lengths of the temperature sensor are set

DECLARATION, CERTIFICATION, CALIBRATION

  • The manufacturer provides an EU declaration of conformity.
  • Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors.
