Measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. These transmitters automatically compensate for errors caused by vibration and temperature changes. Use the keypad to set the pressure range, choose the unit of measure, and zero the transmitter. These transmitters 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. They're often used to indicate a filter is clogged or to maintain a certain pressure in HVAC systems, heat exchangers, chillers, and pumps. All transmitters meet IP66 and NEMA 4X for use in washdown and corrosive environments and have a hastelloy nickel diaphragm to resist harsh chemicals.

Transmitters will only provide accurate readings within the rated pressure range. These 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. They can also be configured using three or four wires.

Safe for use in environments where flammable gases and vapors are present, these transmitters measure the difference in pressure between two process lines without needing to program your receiving device to correct for errors. They meet NEC safety standards for protection against an explosion. These transmitters automatically compensate for errors caused by vibration and temperature changes. 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. You’ll often see them used to indicate a clogged filter or help maintain a certain pressure in heat exchangers, chillers, HVAC systems, and pumps. Rated IP66 and NEMA 4X, they protect against dirt, dust, corrosion, weather, and washdowns, and the hastelloy nickel connection protects against harsh chemicals.

Transmitters will only provide accurate readings within the rated pressure range. Most often, these transmitters connect using two wires. 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.
