Endress + Hauser TMT31-AAA1A1A1+B3C1PA Endress+Hauser Temperature Assemblies and Transmitters

Razz Middle East supplies Endress+Hauser temperature measurement assemblies and head-mounted transmitters in Saudi Arabia, built to order against a configured order code. References beginning TM and TMT are not catalogue items pulled from a shelf; every character after the family name selects a sensor type, an insertion length, a process connection, an output and an approval. The code you quote is the product.

About Endress+Hauser Temperature Assemblies and Transmitters

A temperature measurement point in process plant is usually three parts that are ordered as one. The sensor insert is a Pt100 resistance element or a thermocouple. The thermowell or protection tube isolates that insert from the process so it can be withdrawn without breaking containment. The head transmitter, mounted in the terminal housing on top, linearises the sensor and converts it to a 4-20 mA loop or a digital protocol such as HART, PROFIBUS PA or FOUNDATION Fieldbus. Endress+Hauser codes this as a single string: TMT identifies the transmitter family, TM the assembly, and the block of letters and digits that follows selects each option in a fixed position. Where the string carries a plus sign, everything after it is an additional specification - a certificate, a tag marking, a calibration, an extended approval - and it is part of the identity of the item. Two devices with the same base code and different tails are different products. Because the transmitter can be configured on site, a replacement usually needs its range, sensor type and failure behaviour set before the loop reads correctly.

Endress+Hauser Temperature Assemblies and Transmitters in Saudi Arabia

Temperature is the most instrumented variable in Saudi process industry, and these assemblies sit across it. Refineries and gas plants measure column, reactor and exchanger temperatures; the complexes at Jubail and Yanbu run thousands of loops on reactors, crackers and utility headers; desalination plants monitor brine, feed and product streams; cement kilns and coolers, and Ma'aden's phosphate operations, rely on protected thermometers in hard service. Selection in the Kingdom is driven by three things beyond the process itself. Hazardous-area classification determines whether the transmitter must be intrinsically safe or flameproof, and the certificate is part of the order code. Chloride-bearing and high-temperature service dictates thermowell material and wake-frequency checks. And high ambient temperature affects the transmitter in the head as much as the sensor in the process, which is why head electronics on sun-exposed lines fail earlier than the same device indoors.

Ordering and lead time

Send the complete order code, including everything after the plus sign, exactly as it appears on the device label or in the loop datasheet. Truncating the tail removes the certificate, the tag and the calibration from the specification and produces a device that cannot legally go back into the same loop. If you only have a tag number, the plant instrument index or the original data sheet will carry the code. For a new point rather than a replacement, tell us the process connection, the insertion length, the temperature range, the output protocol and the hazardous-area classification, and the code can be built from those. Configured instruments are made to order, so plan on a three-week lead time to site, delivered duty-paid, and longer where a special material or a witnessed certificate is specified.

Specifications are taken from the supplier's published catalogue data. Confirm against the manufacturer's current datasheet before ordering.
