F&F AT-2U voltage temperature transmitter
- F&F AT-2U voltage temperature transmitter
F&F AT-2U voltage temperature transmitter
Product description
The AT-2U transmitter is designed to measure temperature with an external temperature sensor and convert the measured value to a unified analog output voltage signal in the range of 0÷10 V.
Operation
The AT-2U transmitter continuously converts the resistance of the external temperature sensor to an output voltage signal in the range of 0÷10 V. As a result of the transformation, a voltage proportional to the temperature of the environment in which the temperature sensor is located appears at the output.
The transmitter works in one of two options - with an internal temperature sensor or with an external probe.
The transmitter works with a resistance temperature sensor type KTY81-210 (or analog).
Dedicated temperature probes made by F&F: RT probe or RT2 probe. Probes available separately.
Due to the nature of the input signal, the maximum length of the signal cables (shielded) connecting the module to the analog input should not exceed 20 m in length.
