TX4-100 Shielded 4-conductor transmitter cable, 30.5 m (100') Hu-26 OMEGACARESM extended warranty program is available for models shown on this page. Ask your sales representative for full details when placing an order. OMEGACARE SM covers parts, labor and equivalent loaners. Extended Warranty Program SM * Insert thermocouple Type J, K, T or E Note: “-TC” and “-TH” models come with 1 m (40") of lead wire. For longer lead wire, add suffix “-(#)FT” for additional cost per foot (over 3') to price. For “-RTD” models, additional cost per foot to the price. Example: EWS-TC-K-8FT, wall mount Type K thermocouple sensor with 8' lead wire. Ordering Examples: EWS-TX, temperature transmitter EWS-MB, bracket/wall plate, PSR-24S, power supply, TX4-100 transmitter cable. OCW-3 OMEGACARESM extends standard 1-year warranty to a total of 4 years. EWS-TX shown smaller than actual size.
