Series 2900 Current to Pressure Transducer

Brand: Dwyer Instruments, LLC
Favorite

The Series 2900 Current to Pressure Transducer delivers reliable high performance for the toughest applications in the most hazardous environments.

Its NEMA 4X housing is designed and FM and CSA approved for both intrinsically safe and explosion-proof operation. This unit has advanced circuitry which includes electronic feedback control for superior vibration protection and highly accurate output. 

The 2900 is not position sensitive and the easily accessible zero and span adjustments make field calibration quick and easy. For ease of installation, this model has input and output ports on both the front and back. It is also not vibration sensitive, which makes the 2900 ideal for field mounting on a valve. These features coupled with the unit's compact size help make set-up and installation simple.
