  Dwyer Dh-012 Pressure Controller
   
  DWYER DH-012 PRESSURE CONTROLLER The Series DH Digihelic Differential Pressure Controller is a 3 in 1 instrument possessing a digital display gage, control relay switches, and a transmitter with current output. Combining these 3 features allows the reduction of several instruments with one product, saving inventory, installation time and money. The Digihelic controller is the ideal instrument for pressure, velocity and flow applications, achieving a 0.5% full scale accuracy on ranges from 0.25 to 100 in. w.c.
The Digihelic controller allows the selection of pressure, velocity or volumetric flow operation in several commonly used engineering units. Two SPDT control relays with adjustable dead bands are provided along with a scalable 4-20 mA process output. In velocity of flow modes, a square root output is provided on the 4-20 mA signal to coincide with the actual flow curve. The Series DH provides extreme flexibility in power usage by allowing 120/220 VAC and also 24 VDC power which is often used in control panels.

Programming is easy using the menu key to access 5 simplified menus which provide access to: security level; selection of pressure, velocity or flow operation; selection of engineering units; K-factor for use with flow sensors; rectangular or circular duct for inputting area in flow applications; set point control or set point and alarm operation; alarm operation as a high, low or high/low alarm; automatic or manual alarm reset; alarm delay; view peak and valley process readings; digital damping for smoothing erratic process applications; scaling the 4-20 mA process output to fit your applications range; Modbus communications; and field calibration.

With all this packed into one product it is easy to see why the Digihelic controller is the only instrument you will need for all your pressure applications.

Package did arrive damaged but not sufficiently to be returned whole service was very good and hopefully the product is going to be good I already have one installed in my house and I’m very happy with it so thumbs up for your business
...Toni donati
What can I say, great price, great service, great communication. From order through to delivery I was kept informed of what was happening, goods arrived when I was told they would.
...Duncan Kury
Thanks to My Tub I have been able to obtain two very scarce products to repair my central heating controls. Despite set backs from 3rd party suppliers, the goods were sourced and delivered in good time by My Tub. With my grateful thanks.
...Paul Banks
Really good service - quick and good product. Will use mytub again.
...Mrs Rita Livermore
Got part but feel delivery cost was excessive it was near as much as the product. You need a simple postal mail option for small items.
...Damian Adams
Thanks very much the part you sent me did the trick
...THOMAS ODONOGHUE - TJ ODONOGHUE ELECTRICAL CONTRACTOR
The part did arrive a little later than expected but the members of staff i dealt with, Christine and Rachel kept me updated were very helpful and polite.
...GASFLOW PLUMBING AND HEATING
Thanks for your prompt customer service replies and for reorganising delivery to a different address at short notice. The part arrived promptly the next day.
...Leopold Hugo
My order arrived safely and on time. This is a good firm to deal with and I recommend them
...A M Smith
i recently made an order with you it was ment to cost nothing foe postage and then i recived a phone call from a courier sercice called streamline and it ended up costing me an extra fifteen pound postage what is that all about . not impresed . ------------- ------------- ------------ Hello Mr Adamson I am sorry but you should have been informed of the charge just after your order came through so you could have made an informed desicion. We only deliver free to the main land and this charge would have been unavoideable. Sorry again for the way this took place I am investigating who this came about. Regards Steve Marshall
