2 Introduction

2.1Appropriate use

The IMPAC ISR 320 pyrometer is a stationary, digital pyrometer for non-contact temperature measurement on metals, ceramics, graphite, semiconductors etc. in the range between 700 and 1700 °C.

The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths are used to calculate the temperature. This technique offers the following advantages when compared with standard one-color pyrometers:

The temperature measurement is independent of the emissivity of the object in wide ranges.

The measuring object can be smaller than the spot size.

Measurements are unaffected by dust and other “grey” contaminants in the field of view or by dirty viewing windows.

The pyrometer can also be switched to 1-color mode and used like a conventional pyrometer.

2.2Scope of delivery

Pyrometer, PC adjustment, and evaluation software InfraWin, works certificate, and operating instructions.

Note: A connection cable is not included with the instrument and has to be ordered separately (see Chapter 8, Reference numbers).

2.6Accessories (optional)

Numerous accessories guarantee easy installation of the pyrometer. The following overview shows a selection of suitable accessories. You can find the entire accessory program with all reference numbers in Chapter 8, Reference numbers.

2.6.1Mounting

An adjustable mounting angle is available to easily mount the pyrometer and align it to the measured object.

2.6.2Cooling Jacket

The completely covered water cooling jacket is made from stainless steel and serves to protect the pyrometer if exposed to a hot environment. It is designed for ambient temperatures up to 200 °C.

ISR 320 Manual

Introduction 11

2.6.3Air Purge

The air purge protects the lens from contamination of dust and moisture. It has to be supplied with dry and oil-free pressurized air and generates an air stream shaped like a cone.

2.6.4 90° Mirror

The 90° mirror enables the capture of objects at an angle of 90° to the pyrometer axis.

2.6.5Scanning Mirror

The scanning mirror unit SCA 300 allows the measured object to be scanned over a certain range. The measuring beam of the pyrometer moves straight in one line across the object and collects temperature data of this line. This is useful when used in combination with the maximum value storage (peak picker) to measure objects which move out of the target area. The scanning angle of the mirror is 0 to 12° and the scanning frequency 0 to 5 Hz. Both values are easily adjustable at the scanner.

2.6.6Flange System

The flange system is a modular mounting system to fix the pyrometer on furnaces, vacuum chambers, etc.

Schematic drawing of the flange system

It can consist of e.g. mounting support, tube support with air purge and flange and an open or closed ceramic sighting tube. The mounting support can be equipped with a quartz window for vacuum applications. It may consist of an equipment rack, flange, and an open or closed ceramic tube. The equipment rack can be equipped for vacuum applications with a fused silica.

2.7Transport, Packing, Storage

With faulty shipping, the instrument can be damaged or destroyed. To transport or store the instrument, please use the original box or a box padded with sufficient shock-absorbing material. For storage in humid areas or shipment overseas, the device should be placed in welded foil (ideally along with silica gel) to protect it from humidity.

The pyrometer is designed for a storage temperature of -20 to 80 °C with non-condensing conditions. Storing the instrument out of these conditions can cause damage or result in malfunction of the pyrometer.

Introduction 12

3 Controls and Installation

3.1Electrical Installation

The pyrometer is powered by 24 V DC ± 25% (very well stabilized, ripple max. 50 mV). It is important to ensure correct polarity when connecting the device to the power supply.

To meet the electromagnetic requirements (EMV), a shielded connecting cable must be used. LumaSense offers connecting cables, which are not part of the standard scope of delivery.

The shield of the connecting cable has to be connected only on the pyrometer’s side. If the connecting cable is extended, the shield of the extension also needs to be extended. The shield must be open on the power supply side (switch board), to avoid ground loops.

The connecting cable has wires for the power supply, interface, analog output and external LED switch via contact. The cable includes a short adaptor cable with a 9-pin D-SUB connector. This connector may be used in combination with the RS485 to USB adaptor.

Attention: When connecting the power supply, ensure the polarity is correct.

Once the instrument has been connected to the power supply, it is immediately ready for use. It needs to run for approximately 15 to 30 minutes before achieving full accuracy. The instrument can be switched off by interrupting the power supply or unplugging the electrical connector.

3.1.2Connecting the pyrometer to a PC

The pyrometer is equipped with an RS485 serial interface. With the RS485, long transmission distances can be realized and the transmission is, to a large extent, free of problems. The RS485 also allows several pyrometers to be connected in a bus system.

If an RS485 connection is not available at the PC, it can be accomplished using the RS485 to USB connector. When using a RS485 to USB adapter, make sure that the adapter is fast enough to receive the pyrometer’s answer to an instruction of the master. Most of the commonly used adapters are too slow for fast measuring equipment, so it is recommended to use the

RS485 USB converter “USB nano“ (ref. no. 3 852 600).

3.1.3Connection to RS485

Half-duplex mode: A1 and A2 as well as B1 and B2 are bridged in the 8-pin round connector of the connecting cable, to prevent reflections due to long stubs.

RS485 Bus System

It also safeguards against the interruption of the RS485 Bus System should a connecting plug be pulled out. The master labels mark the connections on the RS485 converter. The transmission rate of the serial interface in Baud (Bd) is dependent on the length of the cable. Values between 1200 and 115200 Bd may be set.

3.1.4Connection schematic for analyzing devices

For temperature indication of the pyrometer, LumaSense offers pure indicators (series DA 4000). LumaSense also offers indicators with features to change pyrometer parameters (DA 6000 and DA 6000-N) as well as a fast digital PID controller PI 6000.

Additional analyzing instruments, including LED digital displays only need to be connected to a power supply and the analog outputs of the pyrometer (exception: the digital display DA 6000
