PyroEpsilon Fixed Infrared Temperature Sensor with Adjustable Emissivity

Temperature Ranges From -20°c To 500°c Two-wire 4-20 Ma Output Adjustable Emissivity Via Continuously Variable 4-20 Ma Input - Measure A Wide Range Of Target Materials Choice Of Precision Optics For Large Or Small Targets Fast Response With High Stability Stainless Steel Housing, Sealed To IP65 Quick And Easy Installation Wide Range Of Accessories Conforms To Industrial EMC Standard The PyroEpsilon is a simple infrared temperature sensor with an adjustable emissivity setting. It is ideal if the target is partially reflective. The emissivity setting is adjustable via a two-wire 4-20 mA input, and can be adjusted continuously using a variable 4-20 mA source.To set the emissivity manually, the optional PyroTune emissivity adjuster is available. The sensor is also compatible with PLC outputs or indicating controllers that can provide a 4-20 mA signal. If no 4-20 mA input is provided, the emissivity setting will revert to 0.95, making the sensor suitable for measuring non-reflective non-metal materials (or painted metals) out of the box. ACCESSORIES Air/Water Cooled Housing (Must be ordered with sensor)The air/water cooled housing allows the sensor to withstand ambient temperatures above the normal 70°C limit. Depending on the degree of cooling required, air or water may be used as the cooling fluid. To prevent condensation forming on the lens, an air purge collar is included with this item. PyroTune The optional PyroTune emissivity adjuster provides a continuous 4-20 mA current signal to the PyroEpsilon sensor. Simple push-button controls allow the emissivity setting to be adjusted. The built-in LCD display shows the emissivity or mA value.   Air Purge CollarThe 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 BracketThe L-shaped fixed mounting bracket offers a rigid support for the sensor and allows fine rotational adjustment about one axis. Adjustable Mounting BracketThe 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.   ORDERINGSelect from the drop down boxes on the top of the page1) Field of View - choose from 2:1 Divergent Optics 15:1 Divergent Optics 30:1 Divergent Optics Close Focus:1 Divergent Optics 2 Temperature Range -20°C to 100°C 0°C to 250°C 0°C to 500°C 3) Optional Cooling Sensor without Cooling Air/water cooled jacket with air purge collar  [to_order_table]  To Order click on the the model below or scroll to the top of the page and pick the model then  click on ADD TO CART button  PART NUMBERS DESCRIPTION 2:1 Field of View IR-CA-PE21LT PyroEpsilon with 2:1 field of view, -20°C to 100°C range IR-CA-PE21LTWJ PyroEpsilon with 2:1 field of view, -20°C to 100°C range, air/water cooling IR-CA-PE21MT PyroEpsilon with 2:1 field of view, 0°C to 250°C range IR-CA-PE21MTWJ PyroEpsilon with 2:1 field of view, 0°C to 250°C range, air/water cooling IR-CA-PE21HT PyroEpsilon with 2:1 field of view, 0°C to 500°C range IR-CA-PE21HTWJ PyroEpsilon with 2:1 field of view, 0°C to 500°C range, air/water cooling 15:1 Field of View IR-CA-PE151LT PyroEpsilon with 15:1 field of view, -20°C to 100°C range IR-CA-PE151LTWJ PyroEpsilon with 15:1 field of view, -20°C to 100°C range, air/water cooling IR-CA-PE151MT PyroEpsilon with 15:1 field of view, 0°C to 250°C range IR-CA-PE151MTWJ PyroEpsilon with 15:1 field of view, 0°C to 250°C range, air/water cooling IR-CA-PE151HT PyroEpsilon with 15:1 field of view, 0°C to 500°C range IR-CA-PE151HTWJ PyroEpsilon with 15:1 field of view, 0°C to 500°C range, air/water cooling 30:1 Field of View IR-CA-PE301LT PyroEpsilon with 30:1 field of view, -20°C to 100°C range IR-CA-PE301LTWJ PyroEpsilon with 30:1 field of view, -20°C to 100°C range, air/water cooling IR-CA-PE301MT PyroEpsilon with 30:1 field of view, 0°C to 250°C range IR-CA-PE301MTWJ PyroEpsilon with 30:1 field of view, 0°C to 250°C range, air/water cooling IR-CA-PE301HT PyroEpsilon with 30:1 field of view, 0°C to 500°C range IR-CA-PE301HTWJ PyroEpsilon with 30:1 field of view, 0°C to 500°C range, air/water cooling Close Focus Field of View IR-CA-PECFLT PyroEpsilon with Close-focus field of view, -20°C to 100°C range IR-CA-PECFLTWJ PyroEpsilon with Close-focus field of view, -20°C to 100°C range, air/water cooling IR-CA-PECFMT PyroEpsilon with Close-focus field of view, 0°C to 250°C range IR-CA-PECFMTWJ PyroEpsilon with Close-focus field of view, 0°C to 250°C range, air/water cooling IR-CA-PECFHT PyroEpsilon with Close-focus field of view, 0°C to 500°C range IR-CA-PECFHTWJ PyroEpsilon with Close-focus field of view, 0°C to 500°C range, air/water cooling [to_order_table]  Downloads PyroEpsilon Data Sheet PyroEpsilon User Manual   General SpecificationsOutput: 4-20 mA (two-wire, on power loop)Accuracy: ± 1% of reading or ± 1°C whichever is greaterRepeatability: ± 0.5% of reading or ± 0.5°C whichever is greaterEmissivity Setting: Adjustable from 0.2 to 1.0 via 4-20 mA inputResponse Time, t90: 240 ms (90% response)Spectral Range: 8 to 14 μmSupply Voltage: 24 V DC (28 V DC max.)Min.

We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because the PyroEpsilon detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere. 2:1 optics are not available on sensors with temperature range 0°C to 500°C as standard.
