Differential pressure switches - Import export

Compressor pressure switch, rated at 150 PSI.

WiDPr-es is a wireless, batteryless differential pressure sensor developed by ESCOM Enhanced Solutions (ESCOM-ES). WiDPr-es harvests its own power from ambient energy sources, making it a self-powered and maintenance-free solution. The sensor transmits data wirelessly using advanced technologies like Wi-fi, LoRa and Bluetooth Low Energy (BLE) enabling real-time pressure monitoring in HVAC systems, filter condition monitoring, and in other industrial filters, etc. No need for kilometers of cables, wiring, cable trays, trenches, conduits, supports, and no need for batteries, battery replacement and disposal, etc. - Wireless, Batteryless, self-powered, Energy harvesting, IoT - Differential Pressure, HVAC filter monitoring - Bluetooth, LoRa, Wi-Fi - Plug & Forget, Maintenance free, No cable, No Battery

The function of a Pressure Switch is to provide a path for an electrical circuit that is triggered at a certain pressure. Example uses are: •Oil pressure warning light in an automobile •Pump controller (turn well pump on and off) •Air compressor control •Industrial process signaling A pressure switch must have a process connection (usually threaded for a pipe or tube) and an electrical contact that is connected to wires or terminals. They may sense rising or falling pressure and most are adjustable, so the contact will engage (or turn on the electrical circuit) at a desired pressure setting. They can be pneumatic (air and gases) or hydraulic (water, oil or fluids) or even strictly mechanical. The internals can be a diaphragm capsule, a small chamber backed by a spring or a bourdon tube. The contact is usually copper points but can also be a mercury (in glass) tip switch. Unlike Pressure Transducers which give an analog electrical signal proportional to the amount of pressure, these
