SANSEL offers PI 542A Model PROCESS INDICATORs are extremely versatile Indicators that can be used for a wide variety of applications. These INSTRUMENT offer extreme reliability and low cost for Process measurement and logging. PI 542A is a Microprocessor based instrumentation ensures accurate readings for all Linear Parameters. A number of programmable features including In-line calibration are standard. All the parameters are saved in a non volatile EEPROM memory which doesn't needs any external battery.
PI 542A can offer relay outputs for signals exceeding set points. Programmable Re Transmission output models are also available in addition to the industry standard 4 -20mA or 0 - 10V DC output. Optional RS 485 (2 wire ) output also provided for PC communication with PC Interface software & also with MODBUS RTU protocol.
