These differential pressure transducers feature a micro-machined silicon capacitive sensor with extraordinary sensitivity, repeatability and stability of output. The small physical size requires less space in a panel, and can be DIN rail mounted for faster installation and neater appearance. Detachable terminal block reduces wiring errors and field wiring time. A green LED indicates the transducer is powered and functioning and also helps locate the transducer in dark ducts, unlit ceilings, and electrical enclosures. Also, brightness varies with pressure. The conduit/plenum mounting kit comes standard.
