The Dwyer pressure monitor series RPME is designed for critical applications with low differential pressures. The transmitter uses a piezo pressure sensor to achieve high accuracy. There is a choice between ±0.5% or ±1% RSS. The RPME has the same dimensions as the Magnehelic which simplifies an upgrade in the field. The pressure monitor is suitable for applications requiring strict pressure monitoring and alarming. The Dwyer RPME can be configured to monitor positive and negative pressures in protected environments such as cleanroom, pharma and hospitals. The pressure transmitter with a fixed segment LCD (with backlight) provides access to pressure, calibration and alarm settings. In addition, the pressure monitor has a built-in status indication with LEDs that turn green within the set pressure range and orange when the pressure range is outside it. Furthermore, the RPME is equipped with 2 adjustable SPDT relays and 4…20 mA analog output.
