NPT1010P, also known as Fast-Speed Pressure Transmitter, is an advanced pressure transmitter with pressure measurement range of 0-1bar or 0-10bar. It has many special features designed to improve accuracy and stability, and is widely used in pressure, flow, and level applications. This article will discuss the application field and working principle of NPT1010P.

Application Field

The versatile and rugged NPT1010P is designed for use in a wide variety of industrial applications such as pressure, level, flow, speed, and position. It is particularly well-suited to applications requiring rapid response time in dynamic fluctuations, such as process automation and control systems, water treatment systems, pump and compressor systems, process industry (chemical, petrochemical, oil and gas, gas turbine, etc.) and HVAC systems.

This pressure transmitter can measure pressure at a wide range of temperatures, from negative 50℃ to 150℃. As it is very corrosion-resistant and has a built-in temperature compensation, NPT1010P is suitable for most aggressive chemicals and liquids. Thanks to its small size and high accuracy, it can be used in locations with space constraints.

Working Principle

The working principle of NPT1010P Is based on the Wheatstone bridge circuit. It uses a strain gauge as the detector element to convert the mechanical pressure signal into an electrical signal that is proportional to the applied pressure. The Wheatstone bridge consists of four resistors, and the applied pressure changes the bridge resistance balance. The deviation from the balance determines the output signal.

The strain gauge is fixed to a diaphragm, and the diaphragm is supported by a tensioning device in order to maintain a fixed distance between it and the diaphragm. A strain gauge is a sensitive electrical component, so when a pressure is applied to it, it changes its resistance value and the balance of the bridge circuit is affected accordingly.

The electronics of the NPT1010P then converts the Wheatstone bridge signal into digital format which can be easily read and interpreted by the controller or display device. The NPT1010P has the option of digital or analog output that allows it to communicate with any typical electronic device.

In conclusion, NPT1010P is an advanced and efficient pressure transmitter that is widely used in industrial applications. As it is robust and reliable, it can provide accurate measurements and can withstand a wide range of temperatures and pressure levels.
