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.

Differential Pressure Transmitters with Electronic Switch Outputs

Get the flexibility of a differential pressure transmitter and a switch in one. These transmitters can work as a traditional transmitter using an analog output but also have electronic switch outputs and IO Link compatibility, making them great for advanced automation applications. Also known as transducers, they measure the difference in pressure between two inputs and convert it to electrical signal. Connect them to your programmable logic controller or receiving device to monitor differential pressure remotely, activate automated controls, or trigger alarms when they reach the set pressure. A digital display lets you monitor the differential pressure and troubleshoot issues at the source. It rotates for readability.

You’ll often see these transmitters used to indicate a clogged filter or help maintain a certain pressure in HVAC systems, pumps, and cooling systems. NEMA and IP rated, they protect against dirt, dust, corrosion, weather, washdowns, and temporary submersion.

Indoor Environmental Meters

Measure airflow, light, humidity, and temperature with a single, pocket-sized tool. These meters have built-in sensors that can detect multiple environmental factors in your plant or office. This helps you maintain safety compliance and track energy efficiency. A data hold function lets you freeze a measurement on the screen, giving you time to write it down. Additionally, they have the memory to store your high and low measurements. These meters are also known as hygro-thermo-anemometers.

They’re CE marked as compliant with European health, safety, and environmental standards.
