PT100 RTD Transmitter for ENVIROMUX-2D, 5D, and 16D

NTI E-RTDT-1562 – Your 100 Ω Platinum RTD Transmitter with 4-20 mA Output

In process industries, data centers with liquid cooling, or validated production environments, every tenth of a degree counts – deviations can ruin expensive batches or endanger critical systems.

The E-RTDT-1562 from NTI is the perfect transmitter for 100 Ω PT100 RTD sensors: it converts the resistance signal into a robust 4-20 mA current signal that can be transmitted interference-free over long distances. With a measuring range of −200 °C to +850 °C (ENVIROMUX system default −67 °C to +392 °C, extendable on request) and an accuracy of ±0.1 °C, this transmitter sets new standards.

Whether in steam lines, cryogenic systems, furnaces, or cooling circuits – combined with the E-S420MA-24V current sensor and a PT100 sensor, it becomes the heart of your ENVIROMUX-2D/5D/16D system.

Imagine this: in a chemical plant in Cologne, a +480 °C reaction line is monitored. The transmitter detects a rise to +485 °C – the ENVIROMUX-16D triggers an alarm, and the control valves close automatically. Response: under 10 seconds. Damage: none. The E-RTDT-1562 turns analog PT100 signals into digital safety.

The technical excellence lies in its flexible configuration: 2-, 3-, or 4-wire connection – depending on cable length and accuracy requirements. The 4-wire mode completely compensates for line losses, ideal for long distances in large facilities.

The 4-20 mA signal is the industrial standard – immune to electromagnetic interference, scalable, and easily integrated into PLC or SCADA systems. The transmitter mounts on a DIN rail, fits any control cabinet, and is powered via the included preassembled power cable (with country-specific plug and tinned wire ends). A practical example: a brewery in Munich monitors the +78 °C mash with a PT100 sensor.

The E-RTDT-1562 transmits the 4-20 mA signal to the ENVIROMUX-5D – at +82 °C the heating stops automatically, keeping the batch perfect. Without the transmitter, the ENVIROMUX system could not read the PT100 signal – the process would be manual, error-prone, and costly. With the E-RTDT-1562, everything is automated, validated, and documented.

Installation is professional yet simple: connect the PT100 sensor (2/3/4-wire), connect the 4-20 mA output to the ENVIROMUX E-S420MA-24V current sensor, connect power – done. The operating temperature range of 0 to +55 °C (storage −40 to +85 °C) allows use in control rooms, technical centers, or production areas.

The compact housing (129 × 104 × 23 mm) saves space. Another scenario: in a Frankfurt data center with immersion cooling, the transmitter measures the oil temperature at +52 °C. At +58 °C the ENVIROMUX-2D sends an SMS – the cooling loop intensifies, servers remain stable. The E-RTDT-1562 is the industry-standard translator between PT100 precision and ENVIROMUX intelligence – robust, scalable, future-proof.
