BOARD USER’S GUIDE

Chapter 1. Product Overview

1.1 INTRODUCTION

This chapter provides an overview of the P T100 RTD Evaluation Board and covers the

following topics:

• What is the PT100 RTD Evaluation Board?

• What the PT100 RTD Evaluation Board kit includes.

1.2 WHAT IS THE PT100 RTD EVALUATION BOARD?

The PT100 RTD Evaluation Board demonstrates how to bias a Resistive Temperature

Detector (RTD) and accurately measure temperature. Up to two RTDs can be

connected. The R TDs are biased using const ant current source and the output voltage

is scaled using a difference amplifier. In addition to the difference amplifier, a multiple

input channel Programmable Gain Amplifier (PGA) MCP6S26 is used to digitally switch

between RTDs and increase th e sca le up to 32 time s.

The output of the differenc e amplif ier is conn ec te d to a 12- bit differenti al

Analog-to-Digital Converter (ADC) MCP3301. The ADC outputs serial data to the

PIC18F2550 using a Ser ial Peripher al Interface (SPI). The dat a is transmitted to a PC

using a USB interface.

A PC Software Graphical User Interface (GUI) is used to acquire the data. The acquired

data is graphed as a real-time stripchart display. In addition, the user can select input

channels, acquisition interval, and stripchart display buffer size.

1.3 WHAT THE PT100 RTD EVALUATION BOARD KIT INCLUDES

This PT100 RTD Evaluation Board Kit includ es:

• The PT100 RTD Evaluation Board (102-00096)

• PIC18F2550 Firmware (USB)

• PC Software GUI

• Analog and Interface Products Demonstration Boards CD-ROM (DS21912)

BOARD USER’S GUIDE

Chapter 2. Installation and Operation

2.1 INTRODUCTION

The PT100 RTD Evaluation Board allows the user to evaluate Microchip’s solution to

accurately measure temperature using RTD. When biasing RTDs to measure

temperature, self-heat due to power d issip ation ha s to be con sidered. R TD resist ance

availability typically ranges from 100Ω to 5,000Ω. In order to measure the output

voltage across the RTD over a wide temperature range, the biasing current has to be

relatively high. This higher current causes more power dissipation through heat and

skews the temperature reading. Microchip’s solution to this challenge is to use the

MCP6S26 Programmable Gain Amplifier (PGA) to increase the sensor dynamic output

range and increase measure ment resolution while significantly reducing th e biasing

current magnitude.

This board co nsist s of a surf ace moun t R TD to m easure the PCB te mperatu re and an

external RTD connector. In addition, the user can connect and measure an external

leaded RTD (2, 3, or 4-Wire) and configure the corresponding jumper to remotely

measure temperature. The multiple input channel PGA adds gain programmability into

the analog circuit. The multiple input channels are used to switch between RTDs and

the gain is used to increase the sensor dynamic range.

The PGA output is connected to a dif f erential amplifier circuit which allows the user to

scale the sensor output. The differential output is digitized using an MCP3301 12-bit

differ ential analog-to-digital conve rter . The data is transm itted to the PC using the USB

interface. A PC Software Graphical User Interface (GUI) is used to obtain and d isp lay

the data in real-time.

2.2 FEATURES

The PT100 RTD Evaluation Board has the following features:

• A surface mount PT100 R TD

• External (2, 3, or 4-wire) RTD connector

• Gain and input channel programmability using MCP6S26 PGA

• MCP3301 12-Bit + sign ADC

Configuration window will be displayed, as shown in Figure 2-3.

FIGURE 2-3: PC Software GUI.

2. Select Enable/Disable for CH0 or CH1 (Channel 0 and Channel 1, respectively).

3. Select PGA gain, ADC sampling rate, and sampling buffer size for the

stripchart display.

4. Use the scroll bar to adju st the differential amplifier gain and Remote or Local

RTD bias currents.

5. Click start to start acquisition, stop to stop acquisition. Reset to Clear buffer.

6. Adjust the digital potentiometer positions to select the differential amplifier gain

and trim the current sources for the local and external RTDs.

7. Double-click the chart. The Chart Configuration window will be displayed.

2.4 FUNCTIONAL DESCRIPTION

2.4.1 The PT100 RTD Evaluation Board

The PT100 RTD Evaluation Board uses surface mount RTD to measure

temperature. An external 2, 3, or 4-wire PT100 RTD can also be connected to measure

temperature in remote locations. The RTDs are biased using a constant current source.

In order to reduce self-heat due to power dissipation, the current magnitude is relatively

low . The small voltage across the RTD is amplified using the MCP6S26 PGA. The PGA

allows the user to digita lly pro gram the amplifier gain and increase the sensor output

range. The output of the PGA is scaled using a differential a mplifier. The differential

amplifier drives a 12-Bit + sign differential ADC, MCP3301. The digital data is read

using PIC18F2550 and transmitted to PC using a USB interface.

2.4.1.1 THE RTD BIASING CONSTANT CURRENT SOURCE

The constant curre nt source uses a reference voltage, one amp lifier, and a PNP

transistor, as shown in Figure 2-4.

FIGURE 2-4: Constant Current Source.

The amplifier maintains constant voltage at the transistor emitter terminal. Therefore,

the emitter and collector currents are constant. The collector current biases the RTD.

The biasing current can be fine tuned by adjusting the 10 kΩ digital potentiometer using

the GUI. A 100Ω, 0.1% resistor is available for system calibration at 0°C (RTD

resist ance at 0°C is 100Ω). This resistor can be jumped using JP1.

When connecting an external PT100 RTD, connect JP2 to External Position.

2.4.1.2 RTD SIGNAL CHAIN

The PGA is used to amplify the small volt age across the R TD. The re ference input pin

of the PGA is connected to the RTD negative terminal and Channel 0 and Channel 1

are connected to the positive terminals of each RT D. This allows only the voltage

across the sensor to be amplified. The PGA has a gain error of ±1% (max.) for gains

greater than 1 V/V. Refer to the datasheet (DS21685) for details.

The RTD negative terminal and the PGA output are connected to the differential

amplifier . The differential amplifier scales the PGA output. The difference amplifier gain

is shown in Equation 2-1.

2.4.1.3 THE GRAPHICAL USER INTERFACE

The GUI uses the USB port to communicate with the PIC18F2550.

When start is clicked, the macro double checks hardware availability before starting

the acquisition .
