Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment. Install them in duct through a hole and connect to your gauge with tubing.
Sensors with pressure tubes give more accurate measurements in applications with high air flow. Style D is held in place with a magnet so you can move it for use in multiple locations.

Quick-Connect Thermocouple Probes for Surfaces
The probe tips come attached to mounting connections for fast installation.
Note: When installing probes with wire leads, the red wire is negative.
Magnetic probes mount on any flat, ferrous surface.

Keep machinery running smoothly by monitoring its health and status from your computer. Often used with electric motors, pumps, and lathes, these kits measure changes in vibration and temperature—identifying equipment problems and potential failures before they occur. Plug in the sensor, set your thresholds, and view data directly on your screen. You’ll also receive email notifications when vibrations move beyond your specified range, making them good for preventative maintenance. These sensors are 20 times faster than our other vibration monitors, and they don’t require devices such as programmable logic controllers (PLCs) to operate.
Sensors mount directly to your equipment. Use the magnetic base for quick installation, or use the threaded hole for a more permanent setup. Once the sensor is hooked up, you can either wire it directly to the receiver or connect it to the wireless transmitter to view data remotely.
Kits with a USB connection link only to your computer for direct and easy monitoring.
Kits with an Ethernet connection can be configured to a wider network, transmit data over longer runs of cable, and integrate into other automated systems, such as a PLC.
