AMETEK pressure transmitter Model 89
| Description Model 89 Pressure Transducer (General Information): The Model 89 pressure transducer has been specially designed to meet the needs of military and/or marine applications and conforms to military specifications. The Model 89 accurately measures pressures and transmits a fully adjustable 4-20 mA output signal for remote display, recording or control. The Model 89 is available in gage, compound, vacuum and absolute ranges from 30”Hg vacuum to 0-6000 psi and differential pressures from 300 inch wtr to 400 psi. Model 89 Gage Pressure Version, QPL-MIL-R-24212C (SH)
Model 89 Differential Pressure Version, QPL-MIL-D-24304B (SH)
The Model 89 transducer is directly interchangeable with existing pressure transducers designed to MIL-Standards. 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. |
