Sealed industrial-grade quality: It adopts a sealed industrial quality overlay to ensure reliability in hazardous environments.
Hidden calibration interfaces for TP7, TP7-C, and TP9: There are usually hidden calibration button positions under the overlay for equipment calibration and adjustment.
Icon printing: Functional icons are printed to help users identify temperature stability, battery status, and menu item application scenarios.
It is mainly used for the maintenance of the following petroleum metering equipment: Custody Transfers
Tank Gauging
Temperature measurement of pipelines, ships, railway tankers, and oil tankers
Petrochemical products: Maintenance and replacement instructions for high-viscosity liquids such as gasoline, diesel, asphalt, molten sulfur, and syrup
When to replace: The front panel film is worn, scratched, or the markings are blurred.
The button markings are unclear, affecting operation.
The sealing performance decreases due to overlay aging. Replacement precautions: Model matching: Ensure to use P9AWIN (specific for TP9-A), not P9WIN (standard version of TP9).
Recalibration: After replacing the probe assembly, the equipment needs to be recalibrated.
Follow the standards: Maintenance should follow IEC/EN 60079-19 (Equipment maintenance standard for explosive gas environments).
Original parts: It is recommended to use ThermoProbe original parts to maintain the validity of the explosion-proof certification. Ordering information Model: P9AWIN
Package contents: TP9-A front panel overlay (including printed markings and button patterns)
Recommended combination: If the housing seal is aging, it is recommended to order P9CASE_GSKT_MOLDED (chassis gasket) at the same time to ensure the overall sealing performance. This product is a key maintenance accessory for the TP9-A series explosion-proof thermometers after long-term use in harsh petrochemical environments. Regular replacement can ensure the clarity of the equipment operation interface and the reliability of the button functions.
