Application

Application

The 4532 ATC performs precise liquid and gas phase average temperature measurement in bulk storage tank applications.

•Standard 2" flange installation

•Overall 18.5m temperature measurement range

Function and system design

Measuring principle

Temperature measurement

•Up to 6 elements spaced evenly over the length of the flexible tube.

•Pt100, Class A elements

Input

Measured variable	Temperature measurement
	Temperature conversion range: -20 ~ +100°C

Measuring range	-20 ~ +100°C (-4 ~ 212°F)

Output

Output signal	• HART protocol (multi drop HART loop connection)

Signal on alarm	Error information can be accessed via the following interfaces and
	transmitted digital protocol (refer to the operation manuals on
	following instruments)
	• Tank Side monitor 4590 TSM
	• 6000 Series Servo Tank Gauge

Auxiliary energy

Load HART	Minimum load for HART communication: 250 W

Cable entry	see technical document

Supply voltage	16 ~ 30VDC (on multi drop HART loop)

Current consumption	Less than 6mA

Performance characteristics

Reference operating	• temperature = +25 °C (77 °F) ±5 °C (9 °F)
conditions	• pressure = 1013 mbar abs. (14.7 psia) ±20 mbar (0.3 psi)
	• relative humidity (air) = 65 % ± 20%

Maximum measured	Typical statements for reference conditions, include linearity,
error	repeatability, and hysteresis:
	• Linearity:
	• Temperature: ±0.15°C (0.27°F) + number of element deviation
	(based on IEC class A standard)
