75HR-2211 Application Field and Working Principle

The 75HR-2211 Panel Indicator is a capacitance measuring instrument designed for surface mount applications in military and commercial equipment. It has a 0.3 to 3V input range and a 0.2V accuracy at all inputs. It features dual field phase switching and signal routing to the LED indicator and is available in both 2 and 4 wire configuration for panel display applications.

The 75HR-2211 is a highly durable product designed to withstand extreme environmental conditions. It features a strong thermal protection system designed to protect the device in temperatures up to 572°F (300°C) and humidity up to 1500 ppm. The units are corrosion resistant and designed for both indoor and outdoor use.

The 75HR-2211 is designed to detect capacitance changes to a maximum value of 2µF. The output for signals routed to the LED is a non-pulsating DC voltage which is proportional to the input capacitance over the operating range. The speed of the scanner is adjustable via potentiometer, with a scan rate of 0.3ms - 10ms.

The instrument is also designed for remote control applications, with a software control interface. This allows the user to connect the instrument to a PC, or other device, to enable remote control of the 75HR-2211\'s signal routing and scanning functions. The 75HR-2211 can also be used as a beacon transmitter, with a bright LED indicator that can be controlled remotely from a distance.

The 75HR-2211 can be used as a pilot light in many industrial and automotive applications, such as automotive pumps, generators, motors, and automation devices. It can be connected directly to signal systems in order to provide a visual indication of system status and provide an alarm function for any system malfunction or failure. The 75HR-2211 is also designed to be used as a deterrent to shoplifters, signaling the presence of an anti-theft device before a thief attempts to steal an item.

The 75HR-2211 is a reliable and cost-effective solution for many applications, providing a quick and easy way to monitor a wide range of capacitance values. The 75HR-2211 is also an ideal choice for signal routing and scanning applications where a low cost indicator and remote control system are required.
