Parameters
Parameter Specification Details / Notes
Yokogawa Model Number 701933 This is the specific part number for the amplifier unit.
Compatible Transmitter Series EJA-E Series Used in models like EJA110E, EJA115E, EJA118E, EJA130E, EJA430E, EJA440E, etc.
Input Signal from the EJA-E series sensor module.
Output Signal 4 to 20 mA DC with HART 5/7 protocol digital overlay. The analog output is linear to the measured process variable.
Communication Protocol HART (Highway Addressable Remote Transducer) Allows for remote configuration, calibration, and diagnostics using a HART communicator or asset management software.
Power Supply 10.5 to 55 V DC (Standard for 4-20mA HART) The power is supplied to the transmitter's terminals, and this amplifier unit operates from it.
Ambient Temperature -40 to 85 °C (-40 to 185 °F)
Relative Humidity 0 to 100%
Vibration Influence Less than ±0.1% of URL (Under typical conditions)
Default Rangeability Up to 100:1 (depending on the specific transmitter model) The amplifier allows for wide adjustment of the range within the sensor's limits.
Adjustments Zero (Lower Range Value) and Span (Upper Range Value) Adjusted via the external screws and a magnetic tool.
Diagnostics Comprehensive self-diagnostics and HART status alerts. Communicated via the HART signal.
