RTD-NPT-72-E-DUAL-MTP-HT-S
Ordering Examples: RTD-NPT-72-E-DUAL-MTP, dual 100 Ω Class “A” DIN Platinum thin-film elements, 3-wire connections, 1⁄4 NPT mounting thread,
72" long PFA insulated cables with MTP connectors. RTD-NPT-72-E-DUAL-MTP-HT, dual 100 Ω Class “A” DIN Platinum thin-film elements, 3-wire
connections, 1⁄4 NPT mounting thread, 72" long fiberglass insulated cables with MTP connectors.
Options: Sensors supplied with MTP connectors standard. For OTP connectors add “-OTP” to model number for an additional cost. For NO connectors
remove “-MTP” from model number for a subtraction in cost (leads will be stripped). For a 3-pin audio connector, add “-TA3F” to the model number for an
additional cost.
