The TD5420 is a digital pressure transducer that is constructed to fit most digital systems that use transistor to transistor and CMOS logic. Is features a fail safe functionality that returns the field reversible output to a maximum of 3 psig making it suitable for Direct Acting Mode. For Reverse Acting Mode, a frequency output of 15 psig is returned in cases of power loss. This digital pressure transducer is equipped with a booster output that generates a maximum flow capacity of 45 SCFM.
