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. 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. As the differential increases, the output signal from the transmitter will increase. 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. Transmitters will only provide accurate readings within the rated pressure range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. All transmitters are rated NEMA 4 for protection in washdown environments.

4-20mA current output transmitters connect 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.

DC voltage output transmitters connect using three wires—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

These transmitters are commonly used to monitor airflow and to indicate when filters in HVAC systems become clogged. They convert the difference in pressure between two points in a low-pressure system into 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. Transmitters will only provide accurate readings within the rated pressure range. They come with a calibration certificate traceable to NIST. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. All transmitters are rated IP67 for protection in washdown environments.

For use in hazardous locations, these transmitters safely measure the difference in pressure between two process lines in flow applications—such as heat exchangers, chillers, and pumps. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

Automatically compensating for error from temperature fluctuations or vibration, these transmitters don’t require additional programming into your receiving device to correct these factors. Set the pressure range with the keypad, select the unit of measure, and zero the transmitter. They convert differential pressure into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls, to monitor pressure or control equipment. Transmitters will only provide accurate readings within the rated pressure range. Maximum pressure is the greatest spike in pressure a transmitter can tolerate without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. Rated IP66 and NEMA 4X, they protect against dirt, dust, corrosion, weather, and washdowns, and the hastelloy connection protects against harsh chemicals.

Most often, these transmitters connect using two wires to send a 4-20mA current output. The same wire that sends a signal to the receiver also powers the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Three- and four-wire configurations are also possible.

Often used with ovens, dryers, and HVAC systems, these switches detect small differences in pressure. When the differential pressure exceeds your setpoint, the switch is activated. Use them to automate controls or activate an alarm in your process. Switches are single pole, double throw (SPDT), so they switch one circuit on or off. They can be wired normally open (NO) or normally closed (NC).

Not only are these switches rated NEMA 4X for protection from dirt, washdowns, and corrosion, they also have an indicator for additional monitoring at the source of your application. Switches operate based on the difference in pressure between two process lines. When the differential pressure exceeds your setpoint, the switch is activated.
