1.1.2 Universal Transmitter Module (UTM)
The UTM is microprocessor based, and is packaged as a field replaceable module, which is built into the P-
1000 enclosure. Circuit functions include a PIC microprocessor, 2-line alphanumeric display, magnetic
programming switches, and a linear 4-20mA DC output. Field wiring is terminated on the bottom side of the
UTM cover. The UTM also provides an LCD contrast adjust pot and a protective input fuse.
1.1.3 Intelligent Sensor Module (ISM)
The ISM is microprocessor-based and is packaged as a plug-in replaceable module to facilitate easy
replacement and minimum downtime. Circuit functions include an electrochemical sensor, pre-amplifier, PIC
microprocessor, and memory data storage.
