XNXR1SS – Replacement Sensor Cartridge for HCl Detection
Oiltech Controls’s Insight
This sensor cartridge delivers precise hydrogen chloride monitoring. It is a direct-fit replacement for S3000 and XNX transmitters. The measurement range is user-adjustable from 10 ppm to 20 ppm in 1 ppm steps. Factory default is 0-10 ppm for standard applications.
- Sensor type: Electrochemical, replaceable cell
- Target gas: Hydrogen Chloride (HCl)
- Measurement range: 10.0 – 20.0 ppm (adjustable in 1 ppm increments)
- Resolution: 0.1 ppm
- Response time (T90): < 45 seconds
- Operating temperature: -20°C to +50°C
- Humidity range: 15 – 90% RH (non-condensing)
- Shipping weight: 3 kg (complete cartridge)
Compatible Transmitters
- Honeywell XNX Universal Transmitter series
- Honeywell S3000 gas detector
- Other Honeywell transmitters that accept electrochemical cells
Key Features & Technical Benefits
- User-adjustable range from 10 ppm to 20 ppm – adapt to site-specific alarm levels
- Fast plug-in replacement – no rewiring or recalibration hardware required
- Long-life electrochemical cell with stable baseline
- Low cross-sensitivity to common interfering gases (CO, H2S, SO2)
- Built-in temperature compensation for consistent readings
Installation & Maintenance
- Swap the old cartridge with the new XNXR1SS in under 2 minutes
- No special tools needed – twist-lock design ensures secure fit
- Perform a zero and span calibration after installation
- Routine maintenance: visual inspection every 3 months, calibration every 6 months
- Storage: keep in original packaging at 0-25°C until use
Professional FAQ – Selection & Experience
Q: How do I know if this cartridge fits my XNX transmitter?
A: All XNX transmitters share a common sensor interface. If your unit is an XNX series with electrochemical option, this cartridge is a direct replacement. Check the transmitter label for “EC” or “electrochemical” support.
Q: Can I set the range to 15 ppm instead of 10 ppm?
A: Yes. The span is adjustable via the transmitter menu. Use the magnetic switch to enter setup mode, select “span”, and enter 15.0 ppm. The sensor output will scale accordingly.
Q: What is the expected sensor life in continuous operation?
A: Under normal conditions (clean air, 20-25°C), the electrochemical cell lasts 24-30 months. In high HCl concentrations (>10 ppm) or high humidity, life may shorten to 18 months. We recommend keeping a spare cartridge on hand.
Q: How do I verify the sensor is working correctly?
A: Perform a bump test with a known HCl gas standard (e.g., 10 ppm). If the reading stays within ±10% of the target, the sensor is healthy. If not, check the calibration or replace the cartridge.
Q: What should I do if the reading drifts after installation?
A: First, ensure the transmitter is powered for at least 2 hours for stabilisation. Then perform a zero calibration in clean air. If drift persists, check for contamination or moisture on the sensor pins. Clean with isopropyl alcohol if needed.
