E+H release temperature transmitter with HART

ENDRESS+HAUSER Australia (E+H) has released the TMT 142, a robust, HART-based, field-mounted temperature transmitter and indicator, meeting Ex d or Ex i hazardous area approvals, suitable for oil and gas industry applications.

The unit comes in a new single chamber housing design available in aluminium or stainless steel.

E+H says the TMT 142 provides highly accurate temperature sensing/transmitting throughout its operating range, within 0.2°C as standard issue, with another model available that provides accuracy within 0.1°C.

The transmitter offers excellent system accuracy with customised transmitter/sensor matching, using the free-of-charge ReadWin 2000 software tool to calibrate the device, automatically calculating co-efficients for polynomial or Callendar-Van Dusen equations from measured values.

The TMT 142 has a brightly illuminated display that shows the measured value in high or low light level conditions. Temperature information is displayed in large bold digits, in addition to percentage bar graph and engineering unit displays.

The unit features galvanically isolated input up to 2000 volts as standard, having passed rigorous electromagnetic compatability (EMC) testing to ensure reliable performance in the noisiest electrical environments.

Power supply voltage is continuously monitored on the 4-20mA control loop to ensure reliable power to the transmitter, triggering an alarm if the power supply voltage drops too low.

The sensor circuit is also continuously monitored with built-in corrosion detection. The analogue output signal can also differentiate between over-range, fault and error signals, according to Namur NE43 standards.

The temperature sensor may be directly connected to the housing in a "head mount" style, or remotely connected via one of the three cable gland entries.

The transmitter can be wall or pipe-mounted using mounting lugs cast directly on the housing body.

"This instrument really looks after itself and offers a high degree of process safety even in the most demanding environments," said Endress+Hauser Australia managing director John Immelman.
