Pressure measurement via PLC: AMS 2710 pressure sensor module for direct connection

AMSYS GmbH & Co. KG For pressure measurement in devices with integrated SPS/PLC or other modular control, traditional encapsulated transmitters are often too expensive and too large. OEM sensors for soldering are in-expensive, but in addition to their own circuit board, they require various electronic components for adjusting the input and output voltage levels and protection against polarity reversal and short-circuiting. Small, inexpensive pressure sensor modules such as the AMS 2710 with 12..36 V input and 0..10 V output voltage are used in such devices, for example exhaust systems and air filters.

The AMS 2710 series are ready-to-install industrial pressure sensors, which are mounted on a print-ed circuit board and can be easily installed in a housing without additional components, so-called pressure sensor modules. They are available for absolute, relative and differential pressure meas-urement in a wide pressure range from 5 mbar up to 2 bar. The modules are also available as bidi-rectional differential versions (for negative and positive pressure measurement).

These extended pressure sensors have a 0..10 V voltage output at 12..36 V supply. Due to their ro-bust, reverse polarity protected signal output and current limiting, they are thus predestined for in-dustrial environments. Due to the different connection configurations, the AMS 2710 can be con-nected via solder contacts, a plug or a cable terminal strip. The PCB sensor modules are individual-ly calibrated and compensated and achieve a total accuracy of 0.5 %FS in the entire temperature range (-25..85 °C) and in the pressure range > 200 mbar.

In terms of their functionality, the new PCB pressure sensor modules stand between OEM sensors, which have to be soldered onto PCBs with additional components, and ready-to-install, housed pressure transmitters. In addition to the simple connection to existing controllers, the modules can also be used to very easily manufacture individual transmitters with their own housing.

Further variants are the AMS 2711 with 0..5 V voltage output and the AMS 2712 with 4..20 mA cur-rent output. Customized pressure ranges (up to 10 bar) and other modifications are available on re-quest.
