    • Bezel and front cover (with set point knobs and zero adjustment screw) removed to expose Photohelic switch/gage set point mechanism.Cover is clear polycarbonate plastic.
• Gage pointer and light shutter are mounted on helix and balancing counterweight. Shutter passes through slot in optical limit switch to expose phototransistors to integral infrared light source or mask them depending on applied pressure.
• Light shield effectively protects phototransistors from strong outside light sources yet allows free pointer movement. It also gives interior a clean finished look.
• Optical limit switches are used for reliability and long service life. Attached directly to set pointers, they are individually aligned to assure precise switching accuracy.
• Semi-Flexible drive shaft connects to set point knobs.
• Zero adjustment screw connects to screw in cover to adjust zero pressure reading.
• Plastic enclosure protects electronic components and electrical connections.
• Polycarbonate connection or terminal board is self-extinguishing.
• Glass epoxy printed circuit boards for durability and permanence.
• Load relays are DPDT with latching feature for maximum application versatility.
• Electronics are designed to operate on 50/60 Hz, 120 volt current with 10% over or under voltage. Special units for other voltages are available.
• Switch set pointers show switch settings at all times.
• Spring loaded friction clutch prevents operator damage of set point mechanism.
  DWYER A3000 60PA PHOTOHELIC GGE 0-60PA240V Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic gage design. The Photohelic switch/gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating. Two phototransistor actuated, DPDT relays are included for low/high limit control. Easy to adjust set point indicators are controlled by knobs located on the gage face. Individual set point deadband is one pointer width - less than 1% of full scale. Set points can be interlocked to provide variable deadband - ideal for control of fans, dampers, etc. Gage reading is continuous and unaffected by switch operation, even during loss of electrical power. Choose from full scale pressure ranges from a low 0-.25 (0-6 mm) w.c. up to 30 psi (21 bar); single positive pressure to 6000 psig (413 bar).
Photohelic Sensing - How It Works
In typical applications, these Dwyer switch/gages control between high and low pressure set points. When pressure changes, reaching either set point pressure, the infrared light to the limiting phototransistor is cut off by the helix-driven light shutter. The resulting phototransistor signal is electronically amplified to actuate its DPDT slave relay and switching occurs. Dead band between make and break is 1% of full scale or less - just enough to assure positive, chatter-free operation.

Relay-Transformer Features
A plastic housing protects all electronic components. Solid-state and integrated circuit electronics are on glass-epoxy printed circuit boards and self-extinguishing terminal boards.

great service . got my order easily
...george mclafferty
Perfect service, quick delivery of the correct parts and the best price. Excellent.
...James Baron
Received as ordered with thanks. Regards Peter.
...Peter French
I placed an order with MyTub in early September and was informed promptly that there will be a delay in fulfilling this order of some 6 weeks. This presented no problem as I did not want to use this tap straightaway. The very good price charged made it worthwhile the wait. MyTub were very good in the interim period to inform me of the progress and eventually at 5 weeks, the tap arrived, earlier than 6 weeks estimate, in absolutely brand spanking new condition. I have not used this particular tap yet but have used this particular model. It is one of the best types in the market by the name of Grohe. I have every confidence of this tap being no different, when I use it. What more can say about MyTub & Grohe other than sing high praises & recommend the company highly.
...N K Varma
First Class Service!!!!!!!!!! Thank you.
...Kevin Meayers
Cannot fault your service, it was much faster than I expected, thankyou very much.
...Brian Marshall
Problems with stock availability meant that this was not delivered on time, but comms was good and I was kept informed on progress.
...Angus McIntyre
It arrived on the day stated, three was in good order, however the fixing clips and seal were not present. Delivery driver was informed as it came from Wolsey parts center, said he would get one sent out but am still waiting for it. Luckily I was able to use the clips of the existing sink. Very poor.
...Ian Stewart - Stewart Property Services
i cannot in anyway shape or form fault the service I have received from your company and would not hesitate to recommend mytub to any of my friends.
...David Paterson
many thanks for my filter received on schedule, excellent service.
