I to P

Becker I/P Series

Description:

I/P Transducers provide conversion of electronic instrument signal to a pneumatic instrument signal for input to the HPP Series Pneumatic Positioner. The I/P transducer accepts the 4-20 mA analog electronic input signal from the RTU or flow computer and immediately converts to a proportional 3-15 psig pneumatic signal. The I/P transducer exhibits minimal response time and is therefore recommended for applications that require quick stroking times.

Benefits:

I/P Transducer and pneumatic positioner combinations are typically utilized in high speed applications such as power plants and other short systems
The combination of the I/P Transducer and pneumatic postioner provide high gain and fast response time
Minimal bleed
Simple, easy zero and span adjustment
Solid state components
Combatable for natural gas environments

Compatibility:

Pneumatic Pressure Controllers are compatible with all Becker pneumatic positioners including the following:

HPP-2 Model Positioners
HPP-3 Model Positioners
HPP-SB Model Positioners

Nema 4X Enclosure

Range of Product:
Typical Model Utilized:

Fairchild Model TFXI7800-403E
Fisher Model 546
Fisher Model 846
Bristol Model 9110 (lock last output capable- SLOW)

Input Range:

4-20 mA (standard)

Output Range:

3-15 psig (standard)
6-30 mA (alternate)

Note that most I/P transducers fail output to ZERO in event of loss of input signal. Bristol Model 9110 allows lock in last position but is very limited on speed of response.
