Differential pressure transmitter with Modbus communication and Input terminal
The DPT-IO-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-IO-MOD to connect directly to a field communications network. DPT-IO-MOD requires less wiring than traditional 3-wire transmitters, since multiple devices can be connected on serial line. The DPT-IO-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-IO-MOD can read values from one differential pressure measurement point and two temperature measurement points. Hence, the DPT-IO-MOD does the work of three transmitters.

Absolute pressure transmitter for measurement of atmospheric pressure
Special features:
The BA 1000 absolute pressure transmitter is designed to display barometric pressure. At the heart of the unit is an evacuated measurement cell made from an elastic copper material.The deflection of the measurement cell due to atmospheric pressure is measured inductively without making contact. The transducer emits an electrical output signal proportional to the pressure. The device can be powered using a 24 VDC power supply or a variety of AC voltages. The instrument is available with an ISO factory calibration or DAkkS calibration certificate (optional).

High precision differential pressure transmitter P26
Differential pressure transmitter with scalable measuring range and a high level of overpressure protection
The P 26 differential pressure transmitter is designed for pressure monitoring applications in cleanrooms, laboratories, pharmaceutical plants and operating theatres as well as for special uses in machine and plant construction. As well as measuring the differential pressure, the instrument also records positive and negative overpressures as well as flow rates or volumetric flows.
The measuring range is scalable in the range from 10 .. 100 %. Two optional contact points allow the user to connect visual or audible alarms that are triggered any time values rise above or fall below specified limits. The transmitter can be configured easily via an USB interface (optional) with software. This can also be performed using a keyboard and display (optional). The measured values can be displayed in all standard units. A selectable time constant allows the transmitter to be adjusted perfectly to the pressure conditions and thus ensures a stable output signal. The P 26 can be mounted either on a wall or on top-hat rails
