METRIX pressure transmitters are commonly used sensors in industrial practice, widely applied in various industrial automation environments, including water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemicals, oil wells, power, shipbuilding, machine tools, pipelines, and many other industries. Below is a brief introduction to the principles and applications of some commonly used pressure transmitters. Pressure transmitters are used to measure the level, density, and pressure of liquids, gases, or vapors, and then convert the pressure signal into a 4-20mA DC signal output.

METRIX pressure transmitters mainly include capacitive pressure transmitters, diffused silicon pressure transmitters, ceramic pressure transmitters, and strain gauge pressure transmitters. Pressure transmitters can be categorized into three types based on their pressure measurement range: general pressure transmitters (0.001MPa～35MPa), differential pressure transmitters (0～1.5kPa), and negative pressure transmitters.

The main function of the American METRIX pressure transmitter is to transmit pressure signals to electronic equipment, which then displays the pressure on a computer. Its principle is roughly as follows: it converts the mechanical signal of water pressure into an electronic signal such as current (4-20mA). Pressure and voltage or current have a linear relationship, generally a direct proportional relationship. Therefore, the voltage or current output by the transmitter increases with increasing pressure, thus deriving a relationship between pressure and voltage or current. The measured medium in the pressure transmitter is supplied with two pressures: a high-pressure chamber and a low-pressure chamber. The low-pressure chamber uses atmospheric pressure or a vacuum, acting on the diaphragms on both sides of the δ element (i.e., the sensitive element). The pressure is transmitted to both sides of the measuring diaphragm through the insulating plates and the filling fluid within the element.

The American METRIX pressure transmitter consists of a measuring diaphragm and electrodes on both sides of the insulating plates, each forming a capacitor. When the pressure on both sides is inconsistent, the measuring diaphragm shifts, and the amount of displacement is proportional to the pressure difference. Therefore, the capacitance on both sides is unequal. This is addressed through oscillation and demodulation.

Founded in 1965, Metrix's history traces back to seismic measurement technology. Initially focused on geophysical exploration, this technology has also found rich applications in industrial machinery vibration measurement. Therefore, mechanical condition monitoring has become our focus for over 45 years.

Metrix developed the concept of simple, cost-effective mechanical protection with its mechanical vibration switch products, revolutionary 4-20mA vibration transmitters, powerful high-temperature velocity sensors, and innovative influence transmitter technology for reciprocating machinery. In 1998, we acquired PMC/BETA, a world-renowned international supplier of electronic vibration switches. In 2007, Metrix acquired Hardy Instruments, the vibration monitoring division, and its industry-leading portable vibration calibration equipment.

Metrix works as a unit of Roper Industries, a diversified growth company and a component of the S&P 500, Fortune 1000, and Russell 1000 indices. Roper provides engineered products and solutions to global market segments including water, energy, transportation, healthcare, education, and SaaS-based information networks.

Roper offers a strong work discipline while allowing its business considerable autonomy to pursue profit growth. The result is the best of both worlds: Metrix combines the multi-billion dollar stability of Roper's S&P 500 index with the flexibility to focus on delivering solutions and providing better value to our customers every day.

MX2534 Housing Expansion Sensor

Seismic

Seismic vibration instruments are used to measure structural vibrations in bearing housings, piping, machine housings, and machine support structures. It is particularly suitable for machinery with rolling element bearings. These types of bearings send shaft and bearing-related vibrations that can be detected outside the machine by seismic measurements.

METRIX Sensors

Seismic

The sensor provides a dynamic AC output signal in mV/g or mV/inch/sec. Devices with this type of output are typically used to connect to a high-performance vibration monitoring system, rather than general automation and control instruments such as PLCs or DCSs. Metrix offers seismic sensors with a wide range of operating temperatures, frequency responses, size factors, case materials, connector types, mounting options, and hazardous area certifications.
