Page 7: Chapter 2: Installation And Removal Procedures And Notes
If your PT–500E has a vent tube, do not seal, cover, or close the vent tube with anything other than an APG–provided venting cap or desiccant drying cartridge (See Figure 4.1 and 4.2). Unapproved seals or covers will prevent proper sensor operation. -
Page 8: Removal Instructions
Removal Instructions Removing your PT–500E 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. -
Page 9: 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–500E L5 or PT–500E 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 10 Holding Registers (0x03) – PT–500E L5 pressure series Register Function Value Range 40400 Device Address 1 to 247 40401 Units 0-16 40402 Application Type 0 or 8 40403 40404 Decimal (Calculated) 0 – 3 40405 Max Pressure *0 – 32,000 PSI 40406 Full Pressure 0 –...

Page 19: Vent Tube Drying
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). - Page 20 Automation Products Group, Inc.
