Simple to use RTD Transmitters. Scaled -200 to 500 Deg C temperature input & 4-20mA output. Also available scaled as alternate temperature spans. Loop powered 4-20mA RTD temperature transmitter. Signal range can be custom scaled to alternate RTD temperature spans within sensor range. The RTD transmitter allows the simple measurement of industry standard RTDs. Existing RTDs can be connected to modern control systems. RTD transmitters are a simple way to add temperature measurement to a PLC. The RTD is ideally suited for wide temperature ranges and can be used to achieve higher precision than other temperature sensors. Useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryer, and other limited temperature range applications.
