Valve Positioners and I/P Transducers for Pulp Paper and Textile
Paper handling controls and textile processing systems are named applications for the I/P transducer range. These lines run many small pneumatic loops on tension, dosing and air cylinder duty, and they need a low cost converter that turns a controller signal into a stable air pressure without drifting as the mill warms up.
Talk To An EngineerWhat Goes Wrong on These Loops
- Ambient temperature swings in a mill cause output drift in uncompensated converters
- Tension and dosing loops need repeatable pressure, not just approximate pressure
- Small loops multiply quickly, so unit cost and calibration time both matter
- Field calibration is slow when adjustments are not accessible from outside the housing
What Buyers Need From a Supplier
- I/P and E/P transducers with built-in temperature compensation
- External zero and span adjustment so a technician can calibrate without opening the unit
- Compact units that mount close to the cylinder or actuator
- Consistent supply so a mill can standardise on one pattern
Product Ranges for This Sector
Where These Units Get Fitted
- Web tension control where a controller output sets clutch or brake pressure
- Air cylinder positioning on a converting line

Pulp Paper and Textile Questions
Are these transducers temperature compensated?
Yes. A thermistor is fitted in the coil circuit so temperature compensation is performed automatically.
Can zero and span be trimmed in the field?
Yes. Zero and span adjusters are on the outside of the housing so a technician can recalibrate without opening the unit.
Which model should I start with?
Tell us the input signal and the output pressure range you need. The 500X and T1000 patterns cover most general purpose loops; the datasheets are on the downloads page.
Do you supply in mill quantities?
Yes. Large quantities take 7 to 10 days; regular quantities ship from stock in 2 to 3 days.
Can we order these under our own brand?
Yes. OEM and ODM supply includes your logo, your carton and a housing painted in your colour.
