1. 0 5 VDC and 0 10 VDC series Only The zero output 4mA or 0 VDC can be adjusted by holding a magnet perpendicular to the can approximately 1 1 2 from the top or bottom of the can Holding the magnet close to the top of the can increases the output Holding the magnet close to the bottom of the can decreases the output f the zero output values do not change right away hold the magnet in place near the top of the can until the values change for up to two minutes If there is no change repeat the procedure near the bottom of the can If there is still no change consult the factory Unvented PT 500A transmitters do not automatically adjust to changes in barometric pressure We recommend that PT 500A transmitters be zeroed upon receipt and after major weather events NOTE Span calibration must be done at the factory for all analog models O Vent Tube Drying Condensation in the vent tube can damage the electronics in your sensor resulting in unreliable readings APG offers two methods of preventing vent tube condensation a venting cap and a desiccant drying cartridge Common installation methods are cable tie Velcro and cable clamps The venting cap is a PVC tube with a hydrophobic patch that allows moisture to pass out of the tube without allowing water in The cap is sealed by an o ring and is easily installed in the field The desiccant drying cartridge with vent tube adapter absorbs any moisture i2. adequate seal e Always use thread tape or sealant compound on tapered threads Wrap thread tape in the opposite direction of the threads so it does not unravel as you screw the sensor into place Unraveling can cause uneven distribution and seal failure e Always start screwing in your sensor by hand to avoid cross threading Thread failure can be a problem if you damage threads by over tightening them or by crossing threads e For suspension mounting the PT 500 drill a 3 16 hole into the 1 2 NPTF to 1 2 NPTF hex coupler P N 511414 and secure it to the 1 2 NPTM coupler fitting of the PT 500 Attach a 060 diameter 316L SS cable of desired length to the hex coupler and secure the steel cable according to your application requirements IMPORTANT Refer to section 12 for Hazardous Location Wiring PT 500 Series Pressure Transmitters Installation Guide For Analog Output and Modbus Series APG Automation Products Group Inc 1025 W 1700 N Logan UT 84321 www apgsensors com phone 888 525 7300 email sales apgsensors com Part 122950 0004 Doc 9004122 Rev A2 Dimensions 7 40 187 9mm 7 14 181 3mm NON REMOVABLE SENSOR CAGE REMOVABLE ASSEMBLY _ SENSOR CAGE ASSEMBLY 2 24 56 9mm F 2 00 50 8 3 50 88 9mm 03 50 88 9mm f M 6 44 5 29 163 5mm 13
