Endress+Hauser RMA42 Temperature Transmitter Universal transmitter, loop power supply, barrier and limit switch The process transmitter RMA42 displays analog measured values and is controlled by a microcontroller. With the integrated loop power supply, two-wire sensors can be powered. The universal inputs enable the connection of current, voltage, RTDs and TCs. The multicolor LCD display with 7-segment bar graph allows the unit to be displayed. Digital status output Operation using 3 keys Configuration via interface and FieldCare or DeviceCare software One device to cover a multitude of functions and applications: loop power supply, barrier, integrated relays, calculations and indication of measured values. Perfect supplement for level measurements as it can be used as overfill protection, offers calculations like average or difference, e.g. for differential pressure applications and can be used to linearize a tank. Easy on site configuration with 3 buttons and remote commissioning from a safe and convenient location.
