ExTempMini intrinsically safe non-contact infrared temperature sensors measure the temperature of an area of the surface of a solid or liquid, and transmit this as a linear 4-20 mA output. Explosion proof pyrometers typically have bulky, expensive housings, however because the ExTempMini uses Intrinsic Safety as the method of protection, it is compact and low-cost.  Temperature ranges from -20°C to 1000°C are available. All models have an adjustable emissivity setting, and may be used to measure a wide variety of target materials, including food, paper, textiles, plastics, leather, tobacco pharmaceuticals, chemicals, rubber, coal, asphalt and paint. A choice of optics is available to measure small or large targets at short or long distances.

INTRINSIC SAFETY CERTIFICATION
All models of the ExTempMini have been issued an ATEX (CML 22ATEX2007X) Certificate for use in gas explosive atmospheres in above ground installations. The sensing head can be used in all gas Zones including Zone 0. The main enclosure can be installed in Zone 1. The sensing head temperature classification is T3 for ambient temperatures above 115°C.

ACCESSORIES

LCT Loop Configuration Tool (USB Adapter)

LCT Loop Configuration Tool


All ExTemp models are fully configurable via the optional USB adapter (must only be connected on the safe side of the isolator or barrier). The free Windows-compatible configuration software allows the user to rescale the 4-20 mA output, adjust the emissivity setting, and configure averaging, hold processing and reflected energy compensation. The adapter is connected to the measurement loop via mini-hook connectors.  When using the LCT adaptor the free downloadble Calex Config Software may be used for configuration of the sensor and display of the measurement.

 

LCT-485   RS-485 Network Interface

LCT-485   RS-485 Network Interface


This DIN rail-mounted unit provides RS-485 Modbus RTU Slave communications for one ExTemp sensor. It must only be connected on the safe side of the isolator or barrier. It allows up to 224 ExTemp sensors to be connected together in a network.


Air Purge Collar  APM (for sensors with 20:1, Close Focus optics), APMW (for sensors with 2:1 optics)
The air purge collar is used to keep dust, fumes, moisture and other contaminants away from the lens. Air flows into the fitting on the side and out of the aperture at the front.

FBL  Fixed Mounting Bracket
The L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine rotational adjustment about one axis.

ABL  Adjustable Mounting Bracket
The adjustable mounting bracket consists of a fixed mounting bracket plus another L-shaped bracket. When assembled as shown, the adjustable mounting bracket offers a rigid support for the sensor and allows fine two-axis adjustment.

 

Calibration Certificate
UKAS traceable calibration certificate at 3 standard temperature points.
