About the RPS-429A-IS Sensor
The RPS-429A-IS is an intrinsically safe analog ultrasonic sensor available in a variety of ranges. The RPS-429A-IS sensors can be used in hazardous gas or dust environments classified as Zone 0, 1, 2, 20, 21, or 22 for ATEX/IECEx, and Class I, II, or III for C-UL-US when used with approved intrinsic safety barrier(s). See the RPS-429A-IS User Manual and Control Drawing No. Ex202303060 for further information on installation in hazardous locations.
The sensor is self-contained in a 30mm barrel style enclosure, and powered by 14 – 30 V dc with reverse polarity protection.
The RPS-429A-IS is available in two out- put versions. Analog current 4-20 mA 2-wire current loop version or analog voltage 1-5 V 4-wire voltage output version. The analog current or analog voltage are a fixed mA or V per inch based on the maximum range of the sensor. For example, when using the RPS-429AA-40P-IS the output is a linear 0.444 mA per inch, and when using the RPS-429AV-40P-IS the output is a linear 0.111 V per inch.
The RPS-429A-IS has built-in temperature compensation to provide accurate readings throughout the entire operating temperature range.
The sensor is completely sealed and the connection must be made with a cable having a rating of IP66 and/or IP67 or greater.
