WATERTIGHT PRESSURE GAUGE FOR HIGH VOLTAGE CABLES For 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 Dial White anodised Aluminium with black scales Option: Dual scales or special dial markings are available Mounting Direct / Surface Pointer Black anodised aluminium Case & Bezel Grey Cast Iron, grey polyester powder coated, with back flange Scale Ranges 0 to 1 Bar up to 0 to 25 Bar Dual Scale units or custom scales can be provided Movement Stainless Steel Window Acrylic Plastic Window Pressure Element Phosphor Bronze seamless bourdon tube, with Brass body and connection Environmental Rating IP68 as defined in EN 60 529 Traceability 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. Overload Units will withstand overload pressure up to 130% FSD. Pressure Connection 3/8” BSP Other connections available , please contact our Sales Office Certification available BS EN 10204 3.1B Material Certification Point by point Certificate Electrical Contacts Available with independent single, double or triple contacts (see reverse of datasheet for more details) Safety All units are manufactured to comply with EN 837-1 and other regulatory standards including P.E.D. Accuracy Class 1% of FSD as defined in EN837-1 NGTS 3.5.9 Issue 2* Type Tested. Installation instructions Refer to EN 837-2 Temperature Operating: -20 to +90 Degrees C Storage: -40 up to + 100 Degrees C Temperature Effect Variation in indication caused by temperature shall not exceed ± 0.04 x (t2 – t1)% of the span where: t1 is the reference ambient temperature in degrees Celsius t2 is the ambient temperature in degrees Celsius

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. Break on Rising Pressure BR - contacts normally closed but open when rising pressure achieves the pressure setting. Make on Falling Pressure MF - contacts normally open but close when rising pressure achieves the pressure setting. Break on Falling Pressure BF - contacts normally closed but open when rising...
