    Back-Pressure-Regulating Valves for Air and Inert Gas

    Image of Product. Front orientation. Pressure-Regulating Valves. Back-Pressure-Regulating Valves for Air and Inert Gas.
    Often used to protect equipment running on air compressors, these valves obstruct flow to maintain sufficient operating pressure in your system. If the system pressure exceeds the set pressure, they exhaust through the unthreaded relief port. Adjust the set pressure within the range. Valves have two gauge ports.

    Differential Pressure Transmitters with Dial Indicator for Air

    Check the difference in air pressure between two inputs at the source using the dial indicator or remotely using a receiver. The dial indicator on these transmitters operates independently and shows differential pressure in real time for troubleshooting. Also known as transducers, these transmitters convert pressure to an electrical signal that is interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. They are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. All are CE marked, so they meet European safety standards.
    When measuring pressure in ductwork, pair them with a static pressure probe.
    For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. As differential pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range. Connect them using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.

    Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel. Often used in systems running on air compressors, they're installed after pressure-sensitive equipment to obstruct flow and maintain a consistent operating pressure. If the system pressure exceeds the set pressure, they exhaust through the outlet. Adjust the set pressure within the range.

    Differential Pressure Transmitters with Digital Display for Air

    With a digital display and selectable differential pressure ranges, these transmitters are a versatile alternative to transmitters with dial indicators. Unlike a standard transmitter that has one wider differential pressure range, these transmitters have multiple ranges to choose from. The selectable pressure range means they are more accurate than standard transmitters since their accuracy applies to each small range rather than a single wide range. They can also be configured to output either current or voltage, while standard transmitters typically output one signal type. The digital display allows you to troubleshoot and monitor differential pressure at the source. Also known as transducers, they measure the difference in pressure between two inputs and convert it to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. They are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. All are rated UL 94 V-0, so they meet flammability standards. CE marked, they also meet European safety standards.
    When measuring pressure in ductwork, pair them with a static pressure probe. Transmitters with an 8" pressure probe cable include a static pressure probe.
    For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. As differential pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
    Connect them using two wires when using the current output. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. For voltage output, connect them using three wires—two wires into the power supply and a separate wire to send a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

    DIN-Mount Precision Compressed Air Regulators

    Mount these regulators to a 35 mm DIN rail with the included bracket. These regulators have an accuracy of ±0.2%. That makes them ideal for sensitive applications where consistent pressure is needed to generate precise force and movement. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install them in your air line after your filters.
    To mount them on a wall, remove the DIN bracket and use the included wall-mounting bracket.

    High-Accuracy Differential Pressure Transmitters

    At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%. Use them in laboratories or testing applications where the difference in pressure between two points needs to be measured with high accuracy. These transmitters are often used to indicate a filter is clogged or help you maintain a certain pressure in pumps, HVAC, cooling, and other air and liquid systems. They convert differential pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. All transmitters are rated NEMA 4 for protection in washdown environments.
    For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the pressure range and output signal of the transmitter. As the differential increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range. Connect them using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.
