X-Series Data Logger Land-Based Installation

The NexSens PM2 Data Logger Mounting Kit (PM2) is a specially designed mounting kit for X-Series data loggers. It allows for wall mounting with user-supplied screws or pole mounting on a 1.5″ to 2″ (38 to 50 mm) pipe with other system components. The kit includes grounding hardware to protect the system from power surges or spikes.

Grounding a data logger is critically important to ensure measurement accuracy and prevent damage to a data logging system. Damage can either occur acutely or manifest through intermittent hardware problems that are difficult to diagnose and can eventually result in failure. While lightning strikes are an obvious source of power surges that can damage system components, other less commonly thought-of hazards include nearby machinery, other electrical systems, and electrostatic discharge (ESD). Regardless of the environment, measurement systems should always include proper grounding of a data logger and other electronics. Proper grounding helps reduce the risk of expensive damage to the system.

Instructions for installing the data logger are provided below. For more information on proper grounding procedures, please visit the article below:


Land-Based Installation Instructions

For wall mounting, the user must acquire the appropriate screws for the wall material. A 5/16″ hex driver and 9/16″ socket or wrench will be required to install the X-Series logger on the mount. For pole mounting, the user will need a 1/2″ socket or wrench, along with the 5/16″ hex driver and 9/16″ socket or wrench for full installation. Before mounting the data logger in either scenario, ensure the locations of the power source and sensors are within range to connect directly with the logger. The locations should be in a close enough proximity that cables can connect without any strain.

Included equipment:
  • (1) Pole mount bracket
  • (1) X3 Grounding kit (included with logger)
  • (1) 5/16-18 x 2″ U-bolt
  • (1) 3/8-16 x 1-1/8″ Socket head cap screw
  • (2) 5/16″ Split lock washers
  • (2) 5/16″ Flat washers
  • (2) 5/16-18 Nuts
Required Tools:
  • 9/16″ socket or wrench
  • 1/2″ Socket or wrench
  • 5/16″ Hex driver


  1. Gather the PM2 pole mount hardware and the X3 Grounding Kit. Attach the bracket to a wall with the appropriate screws or to a 1.5 to 2″ pole using the included U-bolt, flat washers, lock washers, and nylon nuts.
    1. Tighten the nylon nuts fully using a 1/2″ socket or wrench.
    2. Ensure the grounding cable contacts the bracket during installation.

  1. Align one of the (3) threaded inserts on the bottom of the logger with the mount. It is best to mount the logger with the body tag visible. Insert the socket head cap screw and tighten using a 5/16″ hex driver.
    1. The bolt will sit flush within the mount.

  1. Attach the other end of the grounding cable to one of the other threaded slots underneath the logger.
    1. Ensure the grounding cable contacts the logger during installation.
    2. Use a 9/16″ socket to tighten until the lock washer is flattened.
