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.

• Protection from 15 PSI overpressure & incorrect wiring
• High accuracy at low pressure ranges
• Two package selections allows easy device mounting to best fit application pressure connections
