SERIES 2900
CURRENT TO PRESSURE TRANSDUCER
Intrinsically Safe, Explosion-Proof, NEMA 4X Enclosure
VALVES
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 eld 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 eld
mounting on a valve. These features coupled with the unit’s compact size help make
set-up and installation simple.
BENEFITS/FEATURES
• Designed for hazardous environments
• Vibration resistant
• Explosion-proof
• Weatherproof and intrinsically safe
APPLICATIONS
• Controlling valve actuators, pneumatic valve positioners, air cylinders, clutches,
brakes, dampers, louvers and pumps
