Description
The Keller PD10LHP is a high-precision OEM differential pressure cell designed for demanding industrial applications. Featuring a dual-cell construction, it provides exceptional stability and accuracy in measuring low differential pressures with up to a 600 Bar line pressure. To maintain the integrity of the sensing elements, users should ensure that static line pressure is introduced symmetrically to both ports upon installation. This balanced approach protects the internal dual-cell structure and guarantees long-term calibration stability. Applying the pressure on one side will damage the bridge circuit.
Features
- Optimum long-term stability
- Robust stainless-steel housing
- Front-flush, crevice-free welded diaphragm
- Very high overload resistance
- Line pressure up to 600 Bar
- Optimised thermal behaviour
