Description
Features
- Miniature sensing head and configurable electronics module
- Touch screen (optional) for temperature indication and configuration. Screen changes colour in alarm condition for maximum visibility
- High-ambient sensing heads (optional) withstand up to 120°C or 180°C without cooling
- Adjustable emissivity setting on all models – suitable for a wide range of target materials such as paper, plastics, food, painted surfaces, and many more
- Data logging to MicroSD Card (optional) on touch screen models
- Resistant to interference from movement of sensing head cable – ideal for mounting on robot arms
- 4 to 20mA or RS485 Modbus outputs
- Alarm relay outputs rated 24 vDC (optional) – no need for separate trip amplifier
- Temperature ranges from -20°C to 1000°C
- Maximum, minimum, average and instantaneous readings, peak or valley hold, reflected energy compensation
- Optional mounting brackets, air purge collar and laser sighting tool
- Sensing head sealed to IP65

When the data logging option is selected the electronics module is fitted with a MicroSD memory card slot. The maximum capacity card is 32GB, which will provide logging for up to 28.4 million readings per 2GB. The unit will log the following variables: target temperature, sensing head temperature, electronic module temperature, max, min, average, emissivity setting, reflected energy compensation temperature and alarm events. Data is saved in a CSV format. A new folder is created on the memory card for each day that data is logged and a new log file is created every time logging is started. Units are not supplied with a MicroSD Card but cards are available separately.
Note: Smoke, fumes, dust or steam can contaminate the lens and cause errors in temperature measurement. In these types of environment the air purge collar should be used to help keep the lens clean.
