Transducers USA Introduces New Impact Switch for Pressure Sensing

Transducers USA, an industry leading supplier of audible signal devices, has announced the introduction of a new piezo Impact Switch that functions as a pressure sensor.

ELK GROVE VILLAGE, ILL. (PRWEB) NOVEMBER 06, 2018 - The core piezo disc in the new Impact Switch emits an electrical signal when any pressure is placed on the device. The new switch can also identify changes in movement by impact. Also referred to as a “shock sensor,” Transducer USA’s new Impact Switch can convert the shock of impact to an electrical signal.

In addition to functioning as a switch, the new Model TRPI-2440L(G) can also be used as a receiver. The piezo disc can receive an RF signal, which can cause it to vibrate and emit an alarm-type sound.

The piezo crystal in the new Impact Switch is enclosed in a completely sealed plastic housing, enabling it to be used in liquids, such as cooking oils in restaurants.

As a solid-state device, the TRPI-2440L(G) is immune to most environmental stresses and conditions and will last much longer than capacitance or mechanical switches. The vibrating piezo is the only moving part in this Impact Switch, which provides for a long service life.

The housing for the new Impact Switch includes mounting flanges and a set of lead wires with terminal lugs.
