¡ß Head mounting type multi temperature transmitter ¡ß
¡Ü Model : R911 (With T900)
¡Ü Service intended :
T900 series temperature transmitters are designed to fit into a standard molded terminal heads used on RTD and thermocouple assemblies to provide a 4~20 mA transmission signals. It is a cost effective solution for all temperature measuring process. It is accurate, durable and reliable. Numerous configurations for measurement in many deferent mediums are offered. Generally the transmitter produces a linear 4~20 mA output carried on a two-wire system. The transmitter is supplied factory calibrated, but also has zero and span potentiometers for a field adjustment.
