WATERTIGHT PRESSURE GAUGE FOR HIGH VOLTAGE CABLES Designed specifically to monitor oil pressure within high voltage power cables. The model 510 Watertight HV cable Gauge has to continually operate in the remote severe environments where robustness coupled with repeatability are paramount. The model 510 is designed to meet many International and regulatory standards including ESI 50-1 that requires the gauges to be fully immersible under water and are Type Tested to industry standard NGTS 3.5.9 Issue 2*. Units can be supplied fitted with up to three electrical contacts whose operation can be independently defined and adjusted by use of a removable key. Electrical connections are taken via a three metre PVC insulated and sheathed cable from the side of the case, the wires are colour coded for ease of installation. * Certification available upon request Direct / Surface Case & Bezel Grey Cast Iron, grey polyester powder coated, with back flange Scale Ranges Dual Scale units or custom scales can be provided Pressure Element Phosphor Bronze seamless bourdon tube, with Brass body and Units will withstand overload pressure up to 130% FSD. Pressure Connection Other connections available , please contact our Sales Office Electrical Contacts Available with independent single, double or triple contacts (see reverse of datasheet for more details) Accuracy Class Options: for lower or higher operating temperatures, please contact our Sales Office Temperature Effect Variation in indication caused by temperature shall not exceed t, is the reference ambient temperature in degrees Celsiu: t2 is the ambient temperature in degrees Celsiu: White anodised Aluminium with black scales Option: Dual scales or special dial markings are available Black anodised aluminium Stainless Steel Acrylic Plastic Window Environmental Rating All instruments are individually calibrated and have an unique Serial Number printed on the dial. A Certificate of conformity traceable to National Standards is supplied free of charge. Certification available Point by point Certificate All units are manufactured to comply with EN 837-1 and other regulatory standards including P.E.D. Installation instructions

Electrical Contacts Units can be supplied with up to three independently settable Model 144 electric contacts, each of which can have a different mode of operation as follows :- Make on Rising Pressure MR - contacts normally open but close when rising pressure achieves the pressure setting required Break on Rising Pressure BR - contacts normally closed but open when rising pressure achieves the pressure setting required Make on Falling Pressure MF - contacts normally open but close when rising pressure achieves the pressure setting required Break on Falling Pressure BF - contacts normally closed...
