  Dwyer Dh-004 Pressure Controller
   
  DWYER DH-004 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.

Feedback
Found the product I was looking for easily on the MyTub site. Purchased without difficulty. Was continually kept up to date with my order status and delivery by email. Item arrived in a reasonable time and well packaged. A fantastic experience for my first time order and an excellent service. I will be more than happy to revisit this business for any similar type orders. Thanks.
...Noel Kelly
Placed the order and was contacted by a very helpful chap at MyTubs to say that the part I ordered was obsolete but that they had one to send me. He range back to check that I had ordered the part from the pt number and not by the picture as there is another almost identical. Really chuffed with the customer service. Would recommend.
...Nicola Phillips
good communication, but delivery times are excessively long for no real reason. prices quoted are excellent, although an automatic option for collect at store....without having to 1st pay p&p, then get a refund should be offered. overall very pleased but if I required a part urgently, I would look elsewhere.
...Lee Headington
Although the item took a long time to be delivered I was kept constantly updated about what was happening and my messages were immediately responded to. As I didnt urgently need the item this communication was greatly appreciated.
...Vigo Software Ltd
I couldnt be more pleased with either the service or the quality of the product I have received. The packing of the fragile items was absolutely superb now I only have to get rid of the MOUNTAIN of polystyrene bits which really did their job. The delivery by City Link far exceeded that offered by unreliable myHermes, so I sincerely hope My Tub sticks with this courier. I was also impressed with the quickness with which my initial email enquiry was dealt..... a reply within about 10mins or so, gives a brilliant impression of the kind of service that an eventual order will receive. I will not hesitate to recommend MY Tub to anyone, especially as I have just noticed the Price Match offer on the website. Thanks fora brilliant transaction.
...JUNE WHITEHOUSE
First-class service : helpful, friendly, personal and effective. My only concern is that basin was delivered "bare" not in a cardboard box, or similar and the protective plastic film that should have protected the edges of the basin was perforated or torn in places it will not be clear until the basin is removed from its plastic wrap whether any cosmetic damage was incurred as a result.
...Philip Taylor
Good customer service. Good communication, would definitely use again. Thanks
...Angela Brehaut
Very helpful customer service when I messed up on the transaction.
...David Simpson
product great but delievry driver did not have message to delievr to neighbour. I only received it due to teh quick thinking of the neighbour who spotted the delivery van.
...David Caine
I cannot fault the My Tub service and would recommend it to anyone. This is my second order and I was pleased with the way a slight hiccup was dealt with in regard to non-delivery at the confirmed date due to sickness at the delivery company. On querying the non-delivery through your portal, the issue was promptly pursued and a revised date given. I feel perhaps the wording in the online catalogue could be a little clearer in regard to alternative andor compatible products e.g in regard to my last order Alcona toilet suite under AR1145, under notes you have AR1148 alternative with horizontal as opposed to bottom outlet , AR2342 compatible cistern, AR7815 compatible seat. That said, I did manage to order exactly what I wanted.
