Differential Transmitters

Provides for both visual monitoring and electronic control of very low differential pressure. The 605 Series is ideal for control applications in building HVAC/R systems where local indication is desired during routine maintenance checks or necessary when trouble shooting the system.

Combines very low ranges with exceptional stability, reliability and either ±0.25% or ±0.5% accuracy for the most demanding applications. Certification to NIST standards is included with each unit. Tough stainless steel housing is NEMA 2 rated to protect against moisture and dirt. Use with air and other compatible gases.

With a single digital push button, both zero and span are calibrated properly, nothing else is required.

Designed to measure pressures as low as 0.1 in w.c. with ±0.4% accuracy. The transmitter features 15 psid overpressure, reverse polarity protection and EMI/RFI protection. The NEMA 4 housing allows for versatile mounting locations and integral mounting tabs simplify installation.

Designed for air conditioning and ventilation applications, this differential pressure transmitter measures -100 to 100 Pa with a 4 to 20 mA analog output (4-wire, 24 V AC/DC). Additionally, a magnetic valve performs automatic zero-point adjustment for long-term accuracy. It is available with or without a display.

Measuring differential pressure across a 50 Pa to 2000 hPa range, this transmitter uses automatic zero-point adjustment for high accuracy and long-term stability. Additionally, it calculates flow velocity and volume flow and supports configurable alarm management. It suits differential pressure monitoring between rooms and drying-process control.

Measuring differential pressure from 10 Pa to 1000 hPa, this transmitter maintains positive pressure in controlled environments and calculates flow velocity from the reading. Additionally, an optional probe adds simultaneous humidity and temperature measurement, and automatic zero-point adjustment preserves accuracy. It includes self-monitoring with an early-warning alarm.

Measuring differential pressure from 10 Pa to 10 hPa, this transmitter is built in a flat, cleanroom-conform panel design for flush wall integration. Additionally, an optional probe adds simultaneous humidity and temperature measurement, and automatic zero-point adjustment preserves accuracy. It includes self-monitoring for use in operating theatres and isolation rooms.

Microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and is programmable using HART® Communication. The multiplanar design simplifies installation, saving you time and money during set up.
