Key Spare Parts Selection Guide
O-Rings and Seals
O-rings are key components to ensure the transmitter's protection rating. TMT142C offers two specifications: 88x3 and 18.77x1.78, both made of HNBR 70° Shore with PTFE coating. HNBR has excellent oil and high-temperature resistance, and the PTFE coating reduces friction and enhances sealing effect.
- 71502617: O-Ring 88x3, 5 pcs/pack, suitable for main housing sealing.
- 71502941: O-Ring 18.77x1.78, 10 pcs/pack, suitable for smaller interfaces or sensor connections.
Electronic Module and Housing
The electronic module is the core of the transmitter, model TMT142E-. Note: Due to material classification group ZTA1 restriction, only 1 piece can be ordered per order line. The housing spare part model is TMT142G-, providing a complete replacement solution.
Cable Entry and Adapters
To adapt to different on-site interfaces, the spare parts list provides various adapters and cable glands:
- 51004387: Adapter 1/2NPT to M20X1.5.

- 51006845: Cable gland NPT 1/2, for cable diameter D4-8.5, protection rating IP68.
Explosion-Proof Blind Plugs and Blind Covers
Certified blind plugs are required in explosion-proof areas. The spare parts list lists multiple specifications:
- 71525620: M20x1.5 EEx-d+O-ring, aluminum material.
- 71525622: M20x1.5 Ex-d+O-ring, V4A stainless steel.
- 71525621: G1/2" Ex-d+O-ring, aluminum material.
- 71525623: G1/2" Ex-d+O-ring, V4A stainless steel.
- 51004490, 51006888: Blind covers for sealing unused interfaces.

The mounting bracket 51007995 is made of SS316L stainless steel, suitable for pipe installation with tube diameter 1.5-3 inches. The display housing fixing kit 71310423 comes in packs of 3 for housing assembly.
Maintenance and Ordering Recommendations
To ensure spare parts compatibility, please verify the device model and position number. It is recommended to follow these steps:
- Confirm the transmitter model is TMT142C or TMT142X series.
- Find the corresponding position number and order number based on the faulty part.
- Pay attention to packaging quantity to avoid over-ordering or under-ordering.
- In explosion-proof applications, spare parts with Ex certification must be selected, such as blind plugs, cable glands, etc.
- The electronic module is limited to 1 piece per order line; if multiple pieces are needed, please process separate orders.
Regularly check O-ring aging, and it is recommended to replace every 2 years. When replacing, please use original spare parts to maintain protection rating and explosion-proof performance.
