Series 2900 Current to Pressure Transducer
Specifications - Installation and Operating Instructions
Bulletin V-5
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 Series
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 Series 2900 ideal
for field mounting on a valve. These features coupled with the unit’s
compact size help make set-up and installation simple.
