Product features RS485 Modbus temperature probe - plastic connection head

DESCRIPTION AND APPLICATION

This sensor includes plastic head and stainless steel tube in which a temperature sensor is placed. 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,  protocol communication SD 122K MODBUS/RTU, communication RS485

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 Complies with modified EN 60529. 

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

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

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

ACCESSORIES

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