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 adjustment 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.
