33216 switch Germany wohner model 33216 price

33216 switch is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to a certain rule. Pressure switches typically consist of a pressure-sensitive element and a signal processing unit. According to different types of test pressure, pressure switches can be divided into gauge pressure switches, differential pressure switches, and absolute pressure switches. Pressure switches are one of the most commonly used switches in industrial practice, widely applied in various industrial automation control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation control, aerospace, military industry, petrochemicals, oil wells, electric power, ships, machine tools, pipelines, and many other industries.

33216 switch introduction

Divided into two categories: one is contact type, including single-flange static pressure/dual-flange differential pressure level transmitters, float level transmitters, magnetic level transmitters, submersible level transmitters, electric internal float level transmitters, electric displacer level transmitters, capacitive level transmitters, magnetostrictive level transmitters, servo level transmitters, etc. The second category is non-contact type, divided into ultrasonic level transmitters, radar level transmitters, etc. Static pressure submersible level transmitters (level gauges) are suitable for level measurement of various media in systems and industries such as petrochemicals, metallurgy, electric power, pharmaceuticals, water supply and drainage, and environmental protection. The compact structure, simple calibration, and flexible installation methods provide convenience for users. Standard signal output methods such as 4～20mA, 0～5v, 0～10mA can be selected by users as needed. Using the principle of fluid statics to measure liquid level is an important application of pressure switches. Special cables with ventilation conduits in the middle and specialized sealing technology are adopted, which not only ensure the watertightness of the switch but also allow the reference pressure chamber to communicate with the ambient pressure, thereby ensuring high precision and high stability of measurement.

33216 switch features

1) Since the output of the liquid level is only related to whether the photoelectric probe contacts the liquid surface, and is unrelated to other characteristics of the medium, such as temperature, pressure, density, electricity, and other parameters, the photoelectric level switch has accurate detection and high repeatability; fast response speed, very precise liquid level control, and can be directly installed and used without calibration. 2) Since the photoelectric level switch probe is relatively compact, it can be installed separately in narrow spaces, suitable for use in special tanks or containers. In addition, multiple photoelectric probes can be installed on one measuring body to make multi-point level switches and controllers. 3) Since all components inside the switch are encapsulated with resin, there are no mechanical moving parts inside the switch, so the photoelectric level switch has high reliability, long life, and is maintenance-free.

33216 switch applications

Widely used in water plants, refineries, chemical plants, glass factories, sewage treatment plants, high-rise water supply systems, reservoirs, rivers, oceans, etc., for the measurement and control of static and dynamic liquid levels in water supply pools, distribution pools, water treatment pools, water wells, water tanks, water tanks, oil wells, oil tanks, oil pools, and various liquids.
