Dwyer Instruments has released its new DH3 Series Digihelic Differential Pressure Controller.
The DH3 Series Digihelic Differential Pressure Controller provides a 4-20 mA process output, 2 SPDT relays with adjustable deadbands, and a large, bright backlit LCD display.
The DH3 Series Digihelic Differential Pressure Controller offers simplified programming via a menu key that enables the user to select: security level; set point or set point and alarm operation; auto or manual alarm reset; english or metric engineering units; pressure, velocity or flow operation, K-factor for use with various Pitot tubes and flow sensors, circular or rectangular duct size for volumetric flow operation plus many more.
The Photohelic gauge style aluminium housing is rated IP65 on the front face when properly installed in a control panel.
The sensing element can detect low differential pressures down to 60Pa (0.25˝ w.c.) up to 25kPa (100˝ w.c.). Bidirectional ranges are also available.
These features make the DH3 Series Digihelic Differential Pressure Controller, an ideal instrument for monitoring pressures in various rooms, zones and ducts in factories, laboratories or buildings.
