4532	Introduction

1Introduction

1.1 Introduction

The 4532 Average Temperature Sensor and Converter (ATC) is a multi-element (Pt100) resistance device designed to measure the average product temperature in bulk liquid storage tanks. The measured value is converted into a HART® compatible output for use in temperature compensated volumetric calculations. The 4532 ATC contains up to 6 temperature elements, spaced at 2 or 3 meter intervals along the length of the probe. Power and local HART communications are provided over a 2-wire, intrinsically safe (i.s.) connection from compatible instruments, such as the Varec 6000 Series Servo Tank Gauge (STG), 7500 Series Radar Tank Gauges (RTG) and the 4590 Tank Side Monitor (TSM).

1.2Installation and operation overview

Step 1. Installing on tank top

•The actual installation may require an installer to work in a hazardous area. Safety must be taken into account in order to avoid any harmful conditions.

•The installation method depends on the type of 4532 ATC. Refer to Chapter 4, Installation.

Step 2. Wiring to the host instruments (4590 TSM)

•Wiring material and conditions must be in accordance with intrinsically safe standards.

•One end (normally on the host instrument side) of the shield twisted pair of cables must be grounded at the terminal connection.

•Refer to Chapter 4, Installation.

Step 3. 4532 ATC initial setup

•Set up device settings for the 4532 ATC and the local HART setting to the host instrument.

Step 4. Data flow from the 4532 ATC to the host instruments

•Individual element temperature data: Individual row element temperature can be accessed regardless of liquid level information on the 4532 ATC's data matrix.

Average temperature data: The host instrument sends liquid level data on the HART line to the 4532 ATC. The 4532 ATC calculates both Gas / Liquid phase average temperature based on this given liquid level.
