Sweep: 50-2kHz 5g peak Shock: 1000g peak Random: 16g rms Reference Bulletin V-2 earity and repeatability performance, high proof-and-burst pressure tolerance, and wide operating temperature capability. There are no epoxies or organic materials, such as O-rings, to contribute to signal instability or drift. This robust unit is virtually unaffected by shock, vibration, mounting position, or pressure pulsation. The wide operating temperature range, all-stainless steel wetted materials, high overpressure protection, and highly reliable Ashcroft electronics make the V Series transducer a solid choice for many applications. The V2 transducer meets needs for a variety of demanding OEM applications such as compressor, off-road vehicles and construction equipment, HVAC/refrigeration, Output 4-20mA 1-6 Vdc 1-5 Vdc 0.5-4.5 Vdc1 0.5 to 4.5 Vdc2 10mV/V 1 Nonratiometric Excitation 8-30 Vdc 8-30 Vdc 8-30 Vdc 8-30 Vdc 5V typ.3 5V typ.3 2 Ratiometric Supply Current N/A 10mA typ. 10mA typ. 10mA typ. 5mA typ. 2.5mA @ 5V 3 10V max.
