SEN-TEC TMT130 DE2400135 Product Description

Overview

SEN-TEC TMT130 DE2400135 is a Sen-tec TMT130 universal temperature transmitter for industrial automation and process control. The transmitter converts temperature signals from RTD, TC, mV and ohm input sensors into a standardized 4-20 mA output signal for transmission to a PLC, DCS, controller or display. The DE2400135 number is treated as the manufacturer or internal reference for this TMT130 transmitter. It is designed for compact installation in sensor heads, instrument housings or control panels where standard analog temperature measurement and control signals are required. The TMT130 transmitter is used as a maintenance spare in existing Sen-tec or compatible temperature measurement installations.

Features

SEN-TEC TMT130 supports universal input compatibility for RTD, thermocouple (TC), millivolt (mV) and ohm sensor inputs, allowing one transmitter family to interface with different temperature sensor types. The output is a standard 4-20 mA analog current signal, which matches conventional industrial I/O cards and process control systems. The transmitter operates from a 7.5 to 45 VDC supply range, suitable for common 24 VDC industrial control power arrangements.

The transmitter is built for an operating ambient temperature range of -30 to 65 degrees Celsius. Its compact and lightweight design is intended for straightforward integration into sensor head, instrument enclosure or panel mounting arrangements. The TMT130 provides a dependable interface for accurate temperature measurement in manufacturing processes, HVAC systems, laboratory equipment and general automation. Public distributor data does not confirm sensor element type, accuracy class, sensor probe length, process connection, terminal configuration or enclosure protection for this exact DE2400135 reference; those details should be checked against the original transmitter label or Sen-tec documentation.

Principle

SEN-TEC TMT130 operates as a signal conditioning and analog conversion interface between a temperature sensor and a control system. The connected RTD, thermocouple, millivolt or ohm sensor produces a resistance, voltage or millivolt signal proportional to measured temperature. The transmitter conditions the input signal, converts it to a scaled digital or analog representation, and generates a 4-20 mA output current corresponding to the configured temperature range. The PLC, DCS or controller reads the 4-20 mA loop signal and scales it to engineering temperature units for monitoring, control, alarming or data logging.

The 7.5 to 45 VDC supply powers the transmitter electronics and input conditioning circuit. The transmitter is normally configured for sensor type, measurement range, output scaling and sensor wiring before installation. In operation, the 4-20 mA loop transmits the measured temperature over standard instrument wiring, while fault or sensor-break behavior follows the transmitter configuration and control system input requirements. Replacement should match the original sensor type, range, wiring, supply voltage and output configuration before installation in an existing loop.

Applications

SEN-TEC TMT130 DE2400135 is used for temperature signal conversion in process control, manufacturing lines, packaging machinery, HVAC and ventilation, energy management, water and wastewater, utilities, chemical processing, pulp and paper, food and beverage, pharmaceutical equipment, power and heating systems, laboratory instrumentation, and general industrial automation panels. It fits applications where RTD, thermocouple, mV or ohm sensor signals must be converted to a standard 4-20 mA analog input for PLC, DCS or controller monitoring. In existing Sen-tec TMT130 installations originally equipped with this transmitter, the unit serves as a direct replacement temperature transmitter spare, compatible with the original instrument wiring, supply arrangement and control-system I/O configuration.
