CẢM BIẾN NHIỆT ĐỘ APLISENS MODEL AT-2

Application and function
The temperature economical transmitter AT-2 is applicable to converting resistance of temperature sensor to standard current signal 4…20mA. Most of parameters such as: sensor type, input signal, measuring range may be adapted by user for specific requirements of his measuring system.
Application and function: User define type of sensor, measuring range in the order, the transmitter are programmed with required parameters and their values are printed on serial number label.
