SPD-G – Dual differential pressure transmitter

In order to measure and process the temperature you’ll need a temperature transmitter. These devices feature sensitive temperature sensors for measurement and various outputs to transmit the signal to other devices in the ventilation system. There are different kind of transmitters such as outdoor temperature, dual differential pressure transmitter, … Autotransformers are the core of a transformer fan speed controllers but can also be used in applications that require an AC power supply inferior to the main voltage.
