Norgren R 1/8 Analogue Pressure Gauge 4bar Back Entry 50mm Outside Diameter

Monitor the pressure of gases and liquids in your pneumatic system using this analogue pressure gauge from IMI Norgren. This unit displays pressure readings in both bar and psi (pounds per square inch) for versatility, and its accuracy rating of ±2.5% means you can be confident of reliable results. The stainless steel and ABS (acrylonitrile-butadiene-styrene) body is resistant to impacts and corrosion so it can withstand demanding conditions. A broad operating temperature range between -40°C and +65°C means you can use this device in harsh environments.

• Pressure measurement range between 0 and 4 bar for low-pressure applications
• Outside diameter of 50mm to fit on larger ports
• Rear BSP (British standard piping) tapered thread for quick assembly

• Food industry
• HVAC (heating, ventilation and air-conditioning) systems
• Automotive industry
• Medical equipment

A bourdon tube pressure gauge like this one has an internal curved tube with an oval cross-section. When active, the element being measured presses on the tube, which triggers the external indicator to show the pressure reading. As it's entirely mechanical, it doesn't need an electrical power source.
