AUTROL® Smart Pressure Transmitter are microprocessor based capacitive differential pressure
sensor. It measures the electrostatic capacity to measure the pressure, and generates a 4/20mA
analog output or a HART protocol digital output, transmitting signals to control systems such as DCS
or PLC.
The instrument has an explosion proof housing, with exceptional accuracy and precision, together
providing a reliable system. With the capability of digital communication, the instrument is compatible
with systems requiring high reliability or remote communication.
The transmitter can communicate via HART protocol with a host control system, HHT (HART
Hand-Held Terminal, PC Configurator or PDA Configurator. Accordingly a user may execute Change,
Configure, Test, or Calibration functions on each Parameter of the transmitter from the host via HART
communication. Having an integrated 250ohm resistance, no additional loop resistance is required
when the transmitter is connected to the analog input or output port of the control system. However, a
250~550ohm loop resistance must be connected in series when only DC Power Supply is connected
to the transmitter.
