Pressure Gauges

Pressure gauges are used to measure and display the pressure of a liquid or gas in a system. Pressure systems are designed to operate within a specific pressure range and pressure gauges can indicate if there are pressure changes or leaks that could affect the system performance. Analog pressure gauges utilize mechanical pressure sensing technology and display the measurement using a needle movement on a dial. The needle gives a visual indication of the pressure. They do not require a power supply to operate, but are susceptible to operator error in reading the dial. Digital pressure gauges use an electro-mechanical form of measurement along with circuitry to translate the value to a reading on a display screen. They are more accurate and reliable over a wider temperature range and have remote monitoring capabilities.

Dwyer Mercoid Series EDA Electronic Pressure Controllers incorporate a gage, two switches and a transmitter in one compact package. The front face has LED indicators for switch status and large backlight two-line display showing process value and indication units. Programming is easy with a simple menu structure and external programming buttons. Features include zero set, menu lock out, adjustable dampening, peak and valley indication, adjustable time delay, removable terminal blocks and scalable transmitter output.
