Description

Model 742 Pressure Transducer (General Information): The 742 Pressure Transducer has been specially designed to meet the needs of military and/or marine applications and conforms to military specification MIL-T-24742 (SH). The 742 accurately measures pressure and transmits a fully adjustable 4 to 20 mA or 0-5 VDC output signal for remote display, recording, or control.

Model 742R Gage Pressure Version: The 742R is available in gauge, compound, vacuum and absolute ranges from 30" Hg vacuum to 0-10,000 psi.

Model 742D Differential Pressure Version: The 742D is available in differential ranges from 10 inches of water to 600 psi.

Direct Replacement

The 742D transducer is directly interchangeable with existing pressure transducers designed to MIL-T-24742. The mounting is designed to match the footprint of existing transducers for quick and easy installation.

Minimal Maintenance 

Calibration is quick and easy with the non-interacting zero and span adjustments.
