Commen used integration temperature transmitter, used for the input of thermal resistance,thermocouple,resistance,voltage signal, approved by HART agreement toconfigure, installed inside temperature sensor. 2. Character: It can convert various input signal to 4--20mA output signal. LCD/LED displayed head can be attached and the head could be revolved; 3. approved by HART agreement, use PDA manual station or PC to configure; 4. Through USB interface, external source is dispensable in configuration; 5. There're as many as 11 kinds of thermal resistance output; there's a wide range kinds of thermal resistance input; input value of resistance are wider, reached 10KΩ; input range of voltage is wider, -1000～2000mV; high precision, internal cold-junction compensation; 6. electrical isolated 2KV; easily set-up and operation.
