JUMO dTRANS T01 Two-Wire Transmitter

Overview

JUMO dTRANS T01 is a programmable two-wire transmitter that acquires temperature through an RTD temperature probe or thermocouple, converting the sensor signal into a linearized 4 to 20 mA output. Installed in a terminal head type B or mounted on a DIN rail, the JUMO dTRANS T01 supports connection in two-wire, three-wire, or four-wire circuits for RTD probes, and its Ex-rated version is designed specifically for installation in potentially explosive areas.

As the official authorized partner and exclusive regional representative for JUMO, Seven Star LLC proudly supplies the JUMO dTRANS T01 two-wire transmitter to industrial process and instrumentation customers across Oman and the wider GCC. Every unit shipped through Seven Star LLC is genuine JUMO product with full manufacturer warranty and access to local technical support – ensuring facility engineers and procurement teams in Muscat, Sohar, and Salalah receive an authentic, factory-certified JUMO dTRANS T01 backed by regional service.

Working Principle

The JUMO dTRANS T01 accepts a resistance signal from Pt100, Pt500, or Pt1000 RTD temperature probes, connectable via two-wire, three-wire, or four-wire circuits, or a millivolt signal from a wide range of thermocouple types including J, K, L, U, T, E, N, S, R, B, D, and C, depending on the specific variant ordered. Onboard signal processing linearizes the raw sensor signal – with customer-specific linearization available for non-standard sensor curves – and outputs a standardized, invertible 4 to 20 mA current loop signal, powered entirely by the loop in genuine two-wire fashion.

Configuration is performed via a PC interface using JUMO’s setup software, with the HART version configurable through a HART modem, allowing the measuring range, sensor type, and linearization to be programmed without opening the enclosure in the field. Sensor break and sensor short-circuit detection continuously monitor the health of the connected RTD probe, flagging a fault condition before it can propagate an undetected bad reading into the control system.

Engineering Design of the JUMO dTRANS T01

The JUMO dTRANS T01 operates across an ambient temperature range of -40°C to +85°C (or -25°C to +70°C for the Junior variant), and is powered from a DC 11.5 to 30 V two-wire supply. Calibration accuracy is rated at ±0.05%, and galvanic isolation of 3.75 kV, 2 kV, or 1 kV (depending on configuration) separates the input and output circuits for improved noise immunity and electrical safety.

The transmitter mounts either directly in a terminal head type B or on a standard 35 x 7.5 mm mounting/DIN rail, and the Ex-rated version complies with ATEX and IECEx directives for use in classified hazardous areas, alongside NAMUR NE21 compliance for electromagnetic compatibility. This combination of compact form factor, wide sensor compatibility, and hazardous area approval makes the dTRANS T01 a flexible retrofit option for both new installations and legacy temperature loop upgrades.

Key Features

The JUMO dTRANS T01 combines broad sensor compatibility with precise, field-programmable configuration that makes it a standard choice for two-wire temperature signal transmission.

• Accepts Pt100, Pt500, and Pt1000 RTD probes in two-, three-, or four-wire circuits, plus a wide range of thermocouple types.
• Calibration accuracy of ±0.05% supports demanding process temperature measurement requirements.
• Galvanic isolation up to 3.75 kV between input and output improves noise immunity and electrical safety.
• Sensor break and short-circuit detection flag RTD probe faults before they propagate a bad reading downstream.
• Customer-specific linearization tailors the transmitter’s response to non-standard sensor curves.
• PC-based or HART-modem-based configuration allows field programming without opening the enclosure.
• An Ex-rated version, ATEX/IECEx approved, supports installation in classified hazardous areas.
• Compact installation in a terminal head type B or on a standard DIN rail suits diverse mounting requirements.

Industrial Applications

The JUMO dTRANS T01 is deployed across general process industries, oil and gas, and manufacturing wherever a compact, field-configurable temperature transmitter is needed to convert RTD or thermocouple signals into a standardized current loop output. Typical duties include head-mounted temperature transducer installations, panel-mounted DIN rail signal conditioning, and hazardous-area temperature loops requiring ATEX/IECEx-approved equipment.

As the officially authorized partner for JUMO, Seven Star LLC distributes the JUMO dTRANS T01 to process plants, oil and gas facilities, and industrial operations throughout Oman and the GCC. The transmitter is a strong fit for temperature signal conditioning across the Sohar and Salalah industrial zones, as well as for hazardous-area installations across Muscat that require dependable, ATEX-approved two-wire temperature transmission.
