Pressure warning

The PAC50’s multi-field on-board LCD provides colour-coded visibility even at a distance and is configurable to meet the user’s preferences, so operators are able to monitor process conditions straight from the factory floor, as well as via the control PLC.

The sensor’s high level of functionality offers local and remote IO setting and diagnostic control, a choice of digital and analogue outputs, a wide range of easy mountings and connections, with IP65/67 protection in a rugged polycarbonate housing.

Darren Pratt, SICK UK’s industrial instrumentation product specialist, says: "The PAC50 is ideal for an extensive range of pneumatic control and process functions for automation and packaging to logistics, conveyors and automotive applications. The whole display is back-lit with green or red LEDS which tell you immediately whether you’ve exceeded a set-point or not. It is also designed with a simple, intuitive HMI display, controlled by three buttons for setting parameters and interrogating settings.”

The switch output can be user set to PNP or NPN configurable, and the analogue output to 0-10V or 4-20mA. There is a choice of outputs to suit the factory set-up: 2 digital; 1 digital plus 1 analogue; 2 digital plus 1 analogue, 2 digital including IO-Link, with measuring ranges of  -1 to 0 bar, -1 to +1 bar, 0 to +6 bar and 0 to +10 bar at ±1.5% accuracy.

Simple to set up through a drop down menu or remotely via PLC, the PAC50 simultaneously displays current pressure, units, pressure set limits and switch output status.  The version with IO –Link Stack 1.1 remotely stores parameters to facilitate sensor replacement and instant replacement without recommissioning. Additionally, the SICK Memory Stick allows sensor parameters to be cloned, speeding multi-sensor installation.

Pratt continues: "The flexibility of the PAC50 reduces the need to hold many different replacements in stock as emergency back up. In addition, parameter storage remotely or via the memory stick means minimum plant downtime should any sensor need replacing.”
