Hubbell Pressure switches are usually linked with Air compressor pumps. Air compressor pumps functions at high temperatures as well as in locations where explosions and fire hazards restrict other form of energy. To put it in a nutshell, Hubbell pressure switches essentially tell the pump when to turn on and when to turn off. A more technical description of a pressure switch sounds like this: a device that monitors pressure as well as provides an output when a set pressure is reached. The precise pressure that opens as well as closes the switch is called the set point. Numerous pressure switches are intended for a minimum of 30 PSI as well as a maximum of 50 PSI (or pounds per square inch). So in this instance when the pressure in the system drops to 30 PSI, the switch activates and lets more air flow into the system. Hubbell Pressure switches are comprised of numerous components including an adjustment screw, diaphragm, lever, as well as contacts. The alteration screw sets the ai...

Hubbell Pressure switches are designed to be the most flexible switch on the market, they conveys the user flexibility to build the pressure switch around the compressor, not the other way around. The unloader can be installed on either side, and can be rotated to any of eight various positions, allowing for quicker assembly as well as shorter tubing. A bottom entry frame is also accessible with built in clamping strain relief for even quicker assembly. With thousands of distinctions right off production line, the Hubbell pressure switch offers maximum flexibility at minimum cost. And it is designed to be sold anywhere in the globe. Hubbell Pressure Switches Standard features Hubbell Pressure Switches ·          Contact block replaceable without loss of system pressure ·          Extra wide diaphragm orifice reduces clogging ·          Roomy wiring ...

The pressure switch is an important component in most of our electric models. It is the electric counterpart to the assigned unloader valve. In this blog, we will look at how it works, what it is, and how to adjust? Hubbell pressure switches are used in a number of applications, assembly, and operation of an electric air compressor. Knob/Off level Auto-off/lever which is also known as the knob is used to manually separate the contacts. It is important to turn it to the off position before pluggin in or unplugging the air compressor Terminals The terminals are the points where the incoming and outgoing energy and power leads are connected to the pressure switch. Contacts The contacts are made from a conductive material that consists of 90% silver and 10% nickel; it is used to complete the electrical circuit and allow power to the motor. If it gets separates, the circuit is broken and it will turn off. Diaphragm This is made of a flexible mate...

In this blog, we will discuss the difference between Hubbell pressure switches and Pressure Transducer. The common point is that both pressure transmitter and transducer are generally referred to pressure sensor; it generates and modifies and electrical signal in proportion to medium or measuring variables. When it comes to pressure transmitter, the output signal is a current loop such as 4-20mA or 0-20mA which can be transmitted over very long distances with the same current flow in all parts of the loop. Pressure transducer’s output signal has a voltage of 0-10Vdc, 0/1-5Vdc, 8-24Vdc/ac, 11-30Vdc/ac etc. Now let us look at the difference between Hubbell Pressure switch and pressure transducer! Hubbell pressure switch is more simplistic than pressure transducer whereas the pressure transducer is more advanced and sophisticated than pressure switch. The Hubbell pressure switches can make or break contact which moving into one of the two positions. On the other ...
