Product Usage Instructions

1. System Preparation: Power down the WDG-V analyzer and allow the probe assembly to cool significantly before opening the RTD head enclosure.

2. Mounting: Secure the AMETEK 7000 plate into the head housing using the provided stainless steel screws. Ensure the plate is flush to provide adequate heat dissipation for the onboard electronics.

3. RTD Connection: Connect the RTD probe leads to the terminal blocks on the PCB. Pay close attention to the 3-wire or 4-wire configuration to ensure lead-wire resistance compensation is correctly applied.

4. Calibration: After installation, verify the temperature readings through the WDG-V control unit. A calibration check using a known temperature reference is recommended to ensure the new board is correctly scaled.

Frequently Asked Questions (Q&A)

Q: Why is the “Plate” included in this electronic kit? A: The plate acts as both a structural mount and a thermal barrier. It ensures that the heat from the flue gas probe does not directly damage the sensitive signal conditioning electronics on the board.

Q: Can this kit be used with the older WDG-IV series? A: Generally, no. The 7000-845-SE is specifically optimized for the WDG-V digital architecture and connector pinouts. Always check your analyzer’s serial number for exact part compatibility.

Q: How often should the RTD board be replaced? A: Under normal operating conditions, these boards are designed for long-term use. However, replacement is recommended if the analyzer reports “RTD Open” or “Temp Signal High” faults that cannot be resolved through wiring checks.

Product Industry News
