Pressure sensor, A-1200, G1/4, 0 - 250 bar,1.0%FS, PNP,M12x1,316L - Riegler 148299

Pressure sensor, A-1200, G 1/4, 0 - 250 bar, accuracy 1.0% FS, 1 switching output PNP, IO link, M12x1, 4-wire, housing 316L The model A-1200 is a pressure sensor without display that can be flexibly programmed via IO link and used in a variety of ways. Thanks IO link, the model A-1200 pressure sensor is ideal for use in intelligent machines. To ensure precise measurement results over the long term, the pressure sensor has integrated diagnostic functions that monitor the instrument status and in addition, the model A-1200 can be configured externally and conventiently via the digital signal and adjusted at any time. The robust version of the pressure sensor with IO link has been designed specifically for extreme environmental conditions. With welded M12x1 connector, this can easily withstand shock loads of up to 1000 g. It is designed for medium temperatures between -30 to 100 °C and can therefore be integrated into almost any application. Downtime and associated maintenance expenses and costs decrease significantly due to the stable design. A 360° LED status display provides visual information about the sensor status. The green (OK), yellow (critical state) or red (error) signal enables intuitive and fast error detection and correction. For maintenance, a blinking function via IO link facilitates the clear localisation of a pressure sensor. Confusion is prevented and maintenance is accelerated.

About Pressure sensors

A pressure sensor turns the pressure at the measuring point into an electrical signal the controller can read or use as a switching command. The sensors in this group screw in with a G 1/4 male thread and cover measuring ranges from 0 to 0.4 bar up to 0 to 25 bar. The housing is made of 316L stainless steel.

What matters when choosing

• Measuring range from 0 to 0.4 bar up to 0 to 25 bar: normal system pressure should sit well below the end value, otherwise resolution is lost and pressure peaks run off scale.
• Thread G 1/4 male is the same across the whole group. If the measuring point differs, an adapter or a matching fitting is used.
• Protection IP 65 and IP 67: choose IP 67 wherever splash water or short immersion has to be expected.
• Output signal and electrical connection: the types in this group have a PNP switching output with IO-Link and an M12x1 4-pin connector. IO-Link allows the sensor to be parameterised from the controller.
• Temperature limits: operating temperature -20 °C to 80 °C, medium temperature -30 °C to 100 °C. Both values have to match the measuring point, not only the ambient reading.

Typical applications

• Monitoring network pressure in compressed air systems and compressor rooms
• Limit switching on machines through the switching output
• Pressure measurement on pumps, filters and heat exchangers
• Plants using IO-Link, where readings and parameters travel over the fieldbus
• Test and leak-check benches with changing test pressures

Housing and wetted parts are 316L stainless steel, and protection is IP 65 or IP 67 depending on the version. Manufacturing takes place in Germany.
