F&F AT-2I current temperature transmitter
Product description
The AT-2I transmitter is designed to measure temperature with an external temperature sensor and convert the measured value to a unified analog current output signal in the range of 4÷20 mA.
Operation
The AT-2I transmitter continuously converts the resistance of the external temperature sensor to a DC output signal in the range of 4÷20 mA. As a result of the transformation, a current proportional to the temperature of the environment in which the temperature sensor is located appears at the output.
The transmitter operates in one of two modes - with an internal temperature sensor or with an external probe.
The transmitter works with a resistance temperature sensor type KTY81-210 (or analog).
Temperature probes manufactured by F&F: RT probe or RT2 probe. Probes available separately.
The signal output of the module is protected by an anti-interference filter, which eliminates network interference that affects the accuracy of the transmitted signal. This allows the use of signal cables of up to 300 m in length.
