  • Page 10: Removal Instructions

    • Removal Instructions Removing your PT-500 from service must be done with care. It’s easy to create an unsafe situation, or damage your sensor, if you are not careful to follow these guidelines: • For sensors installed via NPT process connection, make sure the pressure is completely removed from the line or vessel.

    • Modbus Programming with RST-6001 and APG Modbus Software APG RST-6001 Modbus Controller can be used in tandem with APG Modbus to program and control up to 20 PT-500 L5 or PT-500 L31 sensors. Through APG Modbus, you can monitor the raw readings from the sensor, including level or pressure, temperature and battery voltage, or configure the sensor.

  • Page 20: Chapter 4: Maintenance

    • 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. The venting cap is a PVC tube with a hydrophobic patch that allows moisture to pass out of the tube without allowing water in (See Figure 4.1).

    Figure 4.1 Figure 4.2 NOTE: Desiccant crystals change from blue to pink as they become saturated. Car-  tridge must be replaced when all crystals have saturated. • Repair and Returns Should your PT-500 series pressure transmitter require service, please contact the factory via phone, email, or online chat.
