The menu is clear and concise to allow parameters such as set points, reset points, output functions, analog ranges and a range of special options to be easily programmed. The sensors are specified with a switch point accuracy of <= +/- 0.5 percent. The PS400 and PS500 feature a large, bright 4-digit, 7-segment display with a constant indication of pressure in either psi, bar, kPa or MPa. The display is tilted at a 45º angle and can be inverted electronically for easy reading in various applications. The PS500 series also features a process connection that allows the housing to rotate 360º for optimal viewing prior to locking the sensor in place.
