    • 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 500PA PHOTOHLC GG 0-500PA 240V 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.

Had great difficulty sourcing a small waste drainage joint needed to complete a refurb bathroom and My Tub had one and organised a UPS delivery which came 2 days later so job could be finished. For such a cheap part cost I was most grateful that My Tub were prepared to supply this part to me. Thank you for your service, it was much appreciated.
...Linda Crook
Brenda, you are a star. Fantastic customer service. Bought a Myson towel rail element from MyTub that sadly malfunctioned after 18 months. 2 year warranty confirmed by Myson. Brenda went out of her way to arrange a replacement part, having to navigate a challenging supply chain in order to get it to me. Will definately shop with MyTub again. Thank you

First impression counts! I telephoned this company to enquire if they could supply me with a high efficiency, fast recovery Grade 1 copper Cylinder with 28mm coil, constructed for thicker copper sheet 1.7mm2mm rather than normally produced copper thickness cylinders. The company representative who took my initial enquiry was very competent, quick to grasp what I wanted, he suggested options for me to consider, then rang me back within an hour to provide me with a detailed quotation inclusive of delivery. I accepted the quotation and asked for representatives to contact me to arrange payment, and subsequently provide me with prior notification of the delivery date. The entire process from my first call, and subsequent communications were with the same company representative througho
