7.3.2.3 Heat Trace Monitoring

The heat trace monitoring function calculates

the flange temperature based on the capsule

temperature and amplifier temperature measured

with the sensors on the transmitter and generates

alarms when the preset temperature threshold is

exceeded.

The flange temperature is calculated using the

following parameters and formula.

[Parameters]

Parameter

name

Description

Temp 1 (CT)

Module 1 side capsule temperature

(actual measured value using

transmitter’s temperature sensor)

Amp temp

(AT)

Module 1 side amplifier temperature

(actual measured value using

transmitter’s temperature sensor)

Flg temp (FT) Flange temperature (calculated value)

Flg temp coef

(Cf)

Flange temperature coefficient

Flg temp hi

alert val

High temperature error detection

threshold

Flg temp lo

alert val

Low temperature error detection

threshold

[Formula]

Flg temp (FT) = CT + Cf × (CT – AT)

CAUTION

The flange temperature is calculated with the

formula on the assumption that the capsule

part (pressure-detector section) of the module

1 side transmitter is heated or kept warm by an

electrical heater or steam. In room temperature

or less, a slight error (approximately 3 to 4 °C)

may occur because the amplifier temperature is

higher than the capsule temperature.
