Profile

Various versions with overlapping adjustment ranges are available. These cover the overpressure range of 5 mbar to 12 bar, as well as the vacuum range of -5 mbar to -700 mbar.

he switching pressure can be adjusted without a manometer at the adjustment knob with the guide value scale. Various versions are available for this with overlapping adjustment ranges of between 0.2 mbar and 50 mbar. The pressure switch is equipped as standard with a transparent cover, protection class IP54.

The switching pressure can be set at the central adjustment screw with a screwdriver. Various versions are available with overlapping adjustment ranges of between 0.4 mbar and 5 mbar.

The pressure transmitters operate with a piezoresistive pressure sensor as the active element for continuous pressure monitoring. All pressure transmitters optionally have voltage or current interfaces. Certain designs can also be fitted with switching outputs. The manometers are also equipped with a digital display.

The standard pressure transmitter in the IP 50 plastic housing is available with plug or cable connection. The pressure connection is designed as a pipe connection.

This universal series with red LED display and optional relay output is designed for installation in control panels and switchboards. There is IP 20 protection on the front.

This series has an IP 65 ABS plastic oder metal housing and is designed for industrial applications.

This differential pressure transmitter in the IP 54 plastic housing, optionally with LED display, can be fastened directly using molded mounting eyes. The electrical connection is by a cable conduit to screw terminals. The pressure connection to the process is made by means of hose connections.

DPT Series pressure transmitters represent the latest development in their class. Each device is individually temperature compensated to guarantee exact measurement in all conditions. fully automated zero point calibration, AZ calibration, offer reliability in the most sensitive of applications. In addition, it provides cost saving completely maintenance free.

while DPT - R8 offers up-to eigh measurement rannges in a sinngle device. DPT - MOD makes two- way communication possible over modbus network

DPT-R8 series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The most technologically advanced transmitters on the market measuring static and differential pressure, with field selectable units, range and output, all in a single device.

DPT-R8 series devices include:

• Multiple measurement units, field selectable via jumper, including: inWC, mmWC, Pa, mbar.
• 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper (see Product Information).
• Proportional output options including: voltage (0–10 V) and current (4–20 mA).

DPT-2W series differential pressure transmitters are engineered for building automation in the HVAC/R industry. The DPT-2W measure static and differential pressure and they have a field selectable range.

DPT-2W series devices include:

• 8 field selectable measurement ranges, unidirectional or bi-directional, selectable via jumper, (see Product Information)
• Pressure measurement in Pa
• 4-20 mA 2-wire current loop configuration

The DPT-MOD differential pressure transmitter for air conforms to Modbus over serial line protocol using RTU transmission mode and RS485 interface. The digital output signal is sent over Modbus enabling the DPT-MOD to connect directly to a field communications network.

DPT-MOD requires less wiring than the traditional 3-wire transmitters since multiple devices can be connected on serial line.

The DPT-MOD includes an Input terminal that enables reading of multiple other signals such as temperature or control relays over Modbus.The Input terminal has two input channels designed to accept 0−10 V, ntc10k, Pt1000, Ni1000/(-LG), and BIN IN (potential free contact) signals. For example, DPT-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-MOD does the work of three transmitters.
