RPS-409A-IS3 Intrinsically Safe Ultrasonic Sensor
The RPS-409A-IS3 is an intrinsically safe analog ultrasonic sensor designed for use in hazardous gas and dust environments, making it suitable for classified locations such as Class I, II, or III. It is engineered for reliable performance in industries like oil and gas, chemical plants, and other hazardous areas. The sensor is available in multiple sensing ranges and is certified for use with approved intrinsic safety barriers, ensuring safe operation in dangerous environments.
Key Features:
- Intrinsically Safe Design: Certified for use in hazardous environments with cUL approvals for Class I, II, and III hazardous locations.
- Sensing Ranges: Offers various sensing ranges, including 4-40″, 6-80″, 10-144″, and 12-216″.
- Analog Voltage Output: Provides a linear 0-10V DC analog output that varies with the distance of the target. The output voltage per inch is based on the maximum range of the unit.
- Temperature Compensation: Built-in temperature compensation ensures accurate readings throughout the entire operating temperature range.
- LED Indicator: The sensor includes an LED indicator that changes from green (no target detected) to red (target detected).
- Sync/Tx Input Line: Allows for connecting multiple sensors to prevent cross-talk or control when the sensor transmits.
- Durable Enclosure: Housed in a robust Polyvinyl Chloride (PVC) enclosure, the sensor provides protection and durability in demanding environments.
Specifications:
- Power Input: 16-30V DC with reverse polarity protection. A minimum of 24V DC must be applied to the safety barrier.
- Input Current: Maximum of 24mA at 24V DC applied to the safety barrier.
- Output: 0-10V DC analog voltage output, short-circuit protected. Load resistance ranges from 100k Ohms to infinity.
- Operating Temperature Range: -40°C to +60°C (-40°F to +140°F).
- Humidity Tolerance: 0-95% non-condensing.
- Enclosure Material: Available in Polyvinyl Chloride (PVC) with IP67-rated sealing.
- Weight: Approximately 118 grams (4.2 ounces) including jam nuts.
