RPS-409A-IS2 Intrinsically Safe Ultrasonic Sensor
The RPS-409A-IS2 Intrinsically Safe Ultrasonic Sensor is an intrinsically safe analog ultrasonic sensor designed for use in hazardous gas and dust environments. This versatile sensor offers a variety of sensing ranges and is ideal for industries such as oil and gas, chemical plants, and other hazardous locations classified under ATEX, IECEx, and UL standards. With built-in temperature compensation and a robust enclosure, the RPS-409A-IS2 provides reliable and accurate readings even in extreme conditions.
Key Features:
- Intrinsically Safe Design: Certified for use in hazardous environments with ATEX, IECEx, and UL certifications.
- Sensing Ranges: Available in multiple sensing ranges, including 4-40″, 6-80″, 10-144″, and 12-216″.
- Analog Voltage Output: Provides a linear analog voltage output that varies with the distance of the target.
- Temperature Compensation: Ensures accurate readings across the entire operating temperature range.
- LED Indicator: Green LED indicates no target, while the LED turns red when a target is detected.
- Sync/Tx Input Line: Allows for connecting multiple sensors to prevent cross talk or control when the sensor transmits.
- Durable Enclosure: The sensor is housed in either PPS or PVC, providing protection and durability in demanding environments.
