Depending on who you talk to, pressure switches fall under the Pressure Sensor category. Some people will tell you that a Pressure Sensor is a device for pressure measurement of gases or liquids. Included in this Pressure Sensor category along with pressure switches are pressure transducers, pressure transmitters, and pressure senders, among other names. This can be a bit confusing because in the world of instrumentation and process control we define a Sensor as a device that detects changes in physical, electrical, or chemical properties and produces an electrical output in response to that change. And just to add even more confusion, the terms pressure sensor, pressure transducer, and pressure transmitter are unfortunately used interchangeably in the industrial world. A Pressure switch is a two-part device consisting of a sensing transducer and an electrical switch. The electrical switch opens and closes at a specific pressure often referred to as the Setpoint. Depending on the switch and the vendor, the switching pressure setpoint may be fixed or adjustable. A transducer is a device that converts one form of energy to another. So, the transducer part of the pressure switch is the piece that comes in contact with the process under test. Then somehow, the transducer has to operate the electrical switch. Vendors produce pressure switches using different types of transducers and different types of switches. A pressure transmitter has a transducer just like a pressure switch. That’s where the similarity ends. The output of a Pressure Transmitter is an analog electrical voltage or a current signal representing 0 to 100% of the pressure range sensed by the transducer. There are two different types of pressure switches: electromechanical and solid-state. Electromechanical pressure switches all have traditional-style mechanical switches with moving parts. There are a variety of different types of transducers that are used to mechanically operate the switch such as Diaphragm and Bourdon type. – Diaphragm switches use a metal diaphragm to operate the switch. – Bourdon tube switches use a bourdon tube to operate the switch. Solid-state pressure switches have no moving parts. Electrical switching is accomplished by operating a semiconductor device such as a bipolar junction transistor or a Field Effect transistor. A typical transducer used on a solid-state pressure switch is a strain gauge Wheatstone Bridge. The term Electronic Pressure Switch is slowly replacing the term Solid-State Pressure Switch. The Electronic Pressure Switch is solid-state but much more versatile. It offers options such as Programmable functions, LED displays, multiple and adjustable output switch configurations such as normally open, normally closed, or both. As with other electrical devices, there are several different symbols used on schematics to represent pressure switches. All pressure switches on a schematic diagram will be shown in their De-energized condition, or in other words, the condition they would be in sitting on a shelf. Deadband is the difference between the setpoint and the point where the switch re-actuates. ============================= If you want to learn more, you might want to review two of our other articles: What is a Pressure Sensor? https://realpars.com/pressure-sensor Pressure Transmitter Explained | Working Principle https://realpars.com/pressure-transmitter ============================= Missed our most recent videos?
