The Maxwell TT-501 Series is a robust and highly versatile threaded thermocouple temperature transmitter engineered for demanding industrial environments. Housed in a rugged, explosion-proof aluminum alloy enclosure, this transmitter delivers reliable and accurate temperature measurement across a wide range of process conditions. An integrated digital display provides clear, on-site readings, while the RS485 (Modbus RTU) communication output enables seamless integration into modern PLC-based control systems, SCADA networks, and building management systems.

With its highly customizable design — featuring multiple thread options (M6, M8, 1/4 BSP, 1/4 NPT), a selection of premium probe materials (304, 316, and 310 stainless steel, brass, and aluminum), and a comprehensive range of lead wire materials — the TT-501 can be precisely configured to meet the exact requirements of any installation. Both grounded and ungrounded junction configurations are available, offering a choice between faster thermal response and electrical isolation to suit the specific demands of each application.

The TC-K4/TC-J4 series is a high-performance, versatile probe-type thermocouple temperature sensor designed for a wide range of industrial, scientific, and process-control applications. The sensor consists of a stainless-steel protective sheath enclosing a precision thermocouple element, terminated with a braided-shield extension lead wire and fork-type (spade) terminal connectors. Four thermocouple calibration types — K, J, T, and E — are available to cover measurement ranges from cryogenic temperatures down to -200 °C up to +1260 °C, accommodating virtually every industrial temperature-measurement requirement.

The probe sheath is manufactured from 304 stainless steel, offering excellent corrosion resistance and mechanical durability. The extension lead wire is protected by a metallic braided shield (aluminium foil + tinned-copper braid) that effectively suppresses electromagnetic interference and ensures signal integrity over long cable runs. Both probe diameter and insertion length are fully customisable, and the lead wire length can be specified to any required dimension. An optional waterproof (IP67) sealed construction is available for use in wet or immersion environments. All products comply with IEC 60584 international standards.
