Selection and Procurement Recommendations
When purchasing TH54 series spare parts, please select the corresponding order number according to the device model and working conditions. For explosion-proof applications, the TA30H terminal head is recommended; for corrosive environments, the TA30R stainless steel terminal head is recommended. Transmitter selection should consider protocol, input type, and safety level.
For SIL applications, TMT82 (SIL 2/3) can be selected. TMT181 and TMT182 have been phased out; alternative models are recommended.
