1.2 Overview of Transmitter
The Mercoid
®
Smart Pressure Transmitter is a microprocessor based
pressure transmitter with a capacitance sensor optimized for draft
measurement. The Model 3200 has a true draft analog range from 0
to 20 mA. This transmitter is explosion-proof, high precision
accuracy, reliability and has digital communication for remote
communication system.
The Model 3200 is enabled with HART
®
communication with Host,
HHT (HART
®
Communicator) or PC Configurator. The transmitter’s
various variables in host are able to be changed, configured and
calibrated by users. The HART
®
Communication between DC power
s
upply and transmitter requires a 250~ 550 Ohm resistance.
1.3 Software Compatibility
The Mercoid
®
Smart Pressure Transmitter's software is implemented
at the factory. The following functions can be configured using a HHT
(HART
®
Communicator).
