●For head or rail mounting ●2-, 3- and 4- wire ●Error signaling in case of sensor break or short-circuit Characteristics The RT420 is a installation resistance thermometer with transmitter. Pt100 temperature probes can be connected (2-, 3- or 4- wire technology). The device has a linearized 4..20 mA current output. The RT420 is fully potted, robust, shakeproof and durable. This makes it particularly suitable for stressing industrial application as well as outdoor usage. The transmitter is factory preset, but can also be configured by the customer via programming tool. This makes customers’ warehousing easier and has the advantages of a freely programmable measuring range. The RT420 is suitable for head or rail mounting depending on design type. The device provides error signaling in case of sensor break or sensor short-circuit.
