Bestech Australia presents the REG21 differential pressure regulators, from Halstrup. These pressure regulators are installed in a control panel and it is designed to display and control the differential pressure of non aggressive gases (for positive and negative differential pressures).
Features of the REG21 differential pressure regulators:
- The pressure is displayed by a 4-digit LED display. The outputs available are an analog output for the actual value as well as two switched outputs. The switched output condition is indicated by LEDs.
- If the in-feed pressure is too high the pressure inlet is shortened by a valve so the pressure canisters are protected against overload. In addition to overload protection, an automatic zero set function is available. Limiting, time constants and hysteresis can be adjusted by using the buttons on the display face. The pressure regulators can be used as a two or three position controllers.
- Automatic zero-point calibration, high accuracy and stability for long periods are standard features. There is very little hysteresis, and measurement is largely independent of temperature. Switching contacts are available as relay or transistor outputs with adjustable switching thresholds.
