HYDROGEN ANALOG CONTROL SIGNAL TRANSMITTER: S4H-Tx-01

 

INDUSTRIAL APPLICATION FOR LONG DISTANCE TRANSMISSION IN REFINERIES, PHARMACEUTICAL, CHEMICAL AND FERTILIZER PLANTS

 

 

S4H-Tx-01 is a Hydrogen control signal device for long range transmission of signal.
  • It is a transmitter device operating on 24V DC current loop for 4 to 20mA output signal.
  • It is designed to engage with user facilities for signal management and subsequent automation.
  • There are no alarm or relay contacts from the device.
  • The range for the span is pre-decided at the input stage, which is set at manufacture in accordance with user requirement. It is flexible for user calibration in-situ at sites of operation
