The Pressure Sensor
The main purpose of the pressure sensors is to measure and control pressure in air, gaseous and liquid media. The pressure sensor is a device whose physical parameters are changed in variability depending on the medium, whether steam, water or gas. Directly to the pressure sensor by converting these parameters into an electromagnetic pulse and digital code, which further routed to the output device. Most pressure sensors have a similar structure. It includes a primary pressure transducer, which in turn consists of a receiver pressure and high-sensitivity element, the secondary signal processing, high housing and output device through which the converted signal is sent on a chain. Typically, the sensors differ from each other to transform the signal. Currently, there is 6 methods: strain gauge, piezoresistive, capacitive, resonant, inductive and ionization.
As implemented by our company piezoresistive pressure sensors used method signal conversion. Piezoresistive technology is based on highly integrated elements of monocrystalline silicon. The choice of silicon is reasonable because it has a fairly high temperature and temporal stability. To measure the pressure in the non-aggressive environments, using the principle Low cost, which is to use sensors as the protection of silicone gel, and without it. If you want to measure pressure in harsh environments, use silicone fluid. In this case, security and accuracy pressure sensor switch is sealed in a metal case, which is divided into two part of the diaphragm made of stainless steel.
Since the signals from most types of sensors are slowly varying, their range is in the very low frequencies. In order to properly convert the signal to digital code, we need to suppress high-frequency part of the spectrum, which consists of the interference and noise information. In this case, the actual use of analog-digital converters slowly varying signals. Such a method often used in the industry. Our site offers the widest range of pressure sensors of various modifications. Nick Khan oftentimes addresses this issue. Each sensor has all the necessary documents certifying that confirm the high quality of the goods. The pressure sensor, the price of which is available for most industrial enterprises are able to provide high accuracy and reliability of measuring the pressure in the range of 25 Pa to 400 Bar. For the correctness and accuracy of measurements of pressure sensors are enclosed in a housing of high strength, which protects the internal electronic control gear from mechanical effects. Widespread use of pressure sensors found in cooling systems, hydraulic systems, pumping stations and industrial plants, where it is necessary to monitor and control the level of pressure gaseous or liquid medium. They are also used for monitoring the pressure in the containers, piping, vehicles, tanks and oil refineries. In case of failure you can always seek a qualified service center to help producers, where you will have all possible assistance and return the performance of the pressure sensor of any type.
