This second generation BA478C loop powered indicating temperature transmitter provides a large, easy to read digital temperature display plus accurate 4/20mA analog and HART® digital outputs. Optional alarm outputs enable under and over temperature warnings to be generated and an optional display backlight enhances display visibility in poor lighting conditions.
The transmitter has a resistance thermometer, thermocouple, resistance or voltage input and may be configured using the front panel push buttons or via HART® digital communication.
The BA478C is intrinsically safe, when protected via a Zener barrier or galvanic isolator the transmitter may be installed in any gas hazardous area.
The instrument can be supplied calibrated to customer’s requirements free of charge and can be labelled to show units of measurement, tag number and application.
Supported by a three year guarantee.
