Electrical Installation

Dimensions (mm)

Loop Configuration Tool (USB Adapter)

All ExTemp models are fully configurable via the optional USB adapter (to be used in the safe area). The included 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.

Air Purge Collar

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.

Fixed Mounting Bracket

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

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.

PID Controllers and Indicators

The ExTemp may be connected to any of our Pixsys indicating controllers for temperature display, PID control and alarm relay outputs. Our panel-mount PID controllers, such as the ATR121 (pictured) are priced from just £72. These indicating controllers are not ATEX or IECEx certified and may only be used in the safe area.
