The black iron casing electric contact pressure gauge is an economical and efficient industrial instrument designed for precise pressure measurement, on-site indication, and electrical signal control. Manufactured in China, this pressure gauge features a durable black iron powder-coated casing along with an effective electric contact control mechanism and a Bourdon tube pressure sensing element. Cost-effective and practical, it is ideal for monitoring and automating the control of non-corrosive, non-crystalline gases or liquids, This versatile instrument is commonly used in various industrial applications, including machinery, chemical processing, HVAC systems, and water supply management. As the pressure of the measured medium enters the Bourdon tube, it causes elastic deformation, which then moves the indicating pointer to display real-time pressure values on the dial, When the indicating pointer reaches the lower limit setting, it triggers the corresponding electrical contact to close, generating an on signal. Conversely, when the pressure reaches the upper limit setting, the upper limit electrical contact activates, providing an off signal. The output signals from these electrical contacts can be directly utilized to trigger alarm devices or control the starting and stopping of pumps and valves, ensuring automatic pressure control and reliable interlocking protection, Choose our factory-supplied black iron casing electric contact pressure gauge for a high-quality and dependable solution tailored to meet your industrial needs
