MLH125PGB06C

MLH125PGB06C is a pressure transducer comes with different output options, including DC voltage (4~20 mA); 6mm diameter diaphragm manufactured in stainless steel. This component is typically used for industrial pressure measurement, such as pumps, compressors or even static lube tanks, pipelines and fittings.It is a reliable and high-precision pressure transducer, offering stable performance even under extreme temperature conditions.

The working principle of MLH125PGB06C pressure transducer is based on piezoresistive technology which enables it to sense the applied pressure and convert this into a proportional electrical signal. Piezoresistive technology uses a combination of micro-machined silicon-on-insulator (SOI) diaphragm with transducer elements. The diaphragm of MLH125PGB06C is constructed from a thin aluminium nitride (AlN)-on-insulator (AlN-on-insulator) platform which has an extremely low temperature coefficient. This ensures the output signal remains stable over a range of operating temperatures, without affecting its accuracy or linearity.

The pressure which is applied on the diaphragm is converted into a voltage or current signal by using Wheatstone bridge circuit, which is a sensor feedback system. It consists of four resistors to measure the tension of the diaphragm when pressure is applied. The Wheatstone bridge circuit helps ensure that the output voltage or current is proportional to the applied pressure. The output voltage and current can be calibrated to compensate for ambient temperature and pressure variations.

When a pressure is applied on the diaphragm of MLH125PGB06C, it bends proportionally to the applied pressure in a non-linear manner. This effect is measured using the Wheatstone bridge circuit and converted into a proportional electrical signal. The electrical signals can then be used as the input for pressure control devices or used to display the pressure readout on different devices such as LCD displays, meters, or PC monitors.

Generally, the MLH125PGB06C is a highly-accurate pressure transducer, ideal for industrial applications. Its resistance to high temperatures and the Wheatstone bridge circuit make it an excellent choice for pressure measurement applications where accuracy and reliability are essential. The transducer also features a small footprint and is lightweight, making it easy to install and maintain.
