Differential Indicator

ZT514 Differential Indicator is designed to measure and display the difference between two process inputs (Input1 – Input2). It is suitable for applications requiring comparative analysis of parameters like pressure, flow, level, and temperature.

  • Differential pressure monitoring
  • Flow and level comparison
  • Process deviation monitoring
  • Displays difference between two inputs
  • Universal input support
  • Programmable high/low alarms
  • Up to 4 relay outputs
  • Analog retransmission (difference or individual inputs)
  • Optional Modbus / GSM connectivity
  • Programmable hysteresis
  • High reliability and accuracy
  • Input: Universal (TC, RTD, mA, V, mV, Cu53, etc.)
