Dwyer Series 668B/D Compact Differential Pressure Transmitters,
Our low cost Series 668B/D Compact Differential Pressure Transmitters are
capable of sensing differential gage pressure with ±0.8% FS accuracy, and converts
this pressure difference to a proportional high level analog output for both unidirectional
and bi-directional pressure ranges. These transmitters can withstand up to 15 psig
overpressure with no damage to the unit. The compact, lightweight design makes
installation simple and easy. Units are protected against incorrect wiring, and include
a protective terminal cover.
