PCB Piezotronics Introduces New
Submersible Accelerometers |
| |
|
PCB Piezotronics, Inc.
introduces a sealed, watertight, integral cable assembly that ensures
signal fidelity is not compromised due to liquid ingress. Available on
many PCB® sensors, this alternative sealing technique is extremely
valuable when used in gearboxes, transmissions, flow tubes and valves,
sealed chemical reactors with mixers, and when measuring structural
reactions to turbulence. In many industries, a component or location
that requires testing or monitoring may be splashed or submerged in
water, oil, or other liquid rendering the test invalid and possibly even
destroying the senor. While consideration must be given to the sensor
housing material, accelerometers are devices that generate electrical
signals. In order to prevent contamination and degradation of the
measurement signal via the cable, it is imperative to protect the signal
transmission path to make certain the liquid will not chemically
compromise the seal; using a PCB sensor with the new watertight integral
cable assembly virtually eliminates worry, downtime, and added expenses,
allowing for continued, accurate measurements. PCB Piezotronics, Inc. is
a global leader in the design and manufacture of force, torque, load,
strain, pressure, acoustic and vibration sensors ... |
