New “smart” KMGD test points integrate a small piezoresistive sensor and an NFC (Near Field Communication) or Bluetooth transmitter. A technician simply taps a smartphone to the test point to read pressure, temperature, and a time-stamped log. These active test points are backward-compatible with mechanical probes, retaining the original functionality.
In simple terms, a test point is a miniature valve or sealed port that allows a technician to tap into a system without shutting it down or disconnecting lines. The KMGD variant is specifically designed for high-cycle environments, offering a leak-tight seal when not in use and a quick-connect interface for diagnostic tools. kmgd test point
Whether you are troubleshooting a pneumatic pick-and-place robot on an assembly line, verifying hydraulic pressure on a log splitter, or commissioning a new HVAC system, remember to locate the KMGD test points first. They are your window into the lifeblood of the machine—pressure. | Feature | KMGD | Schrader (tire valve)
