The PRO 100 and 200 series multiwavelength infrared temperature sensors are designed to accurately measure nongreybody materials in applications where single and dual wavelength sensors cannot. These include aluminium extrusion and molten aluminium streams, iron and steel streams, galvanised and stainless steel production.

The PRO 80 and 90 series dual-wavelength infrared thermometers have been designed specifically with hostile operating conditions and low and variable target emissivity in mind. They are highly recommended for the measurement of low- or variable-emissivity materials, for measurement through optical obstructions, and for measurement of small or wandering targets.

The PRO 40 and 50 series of advanced infrared temperature sensors are ideal for use with targets with low emissivities at high and low temperatures. By operating at short wavelengths they are able to reduce the errors from changing and very low emissivity.

The sensitivity to emissivity variation is one quarter (high emissivity targets) to one tenth (low emissivity targets) that of a long wavelength sensor. For this reason, the PRO series 40 and 50 infrared thermometers are able to provide an accurate and reliable temperature reading where others fail.

PyroSight series sensors feature a variety of input, output, and alarm options to enable advanced process monitoring and control. Each sensor can be configured to operate as a stand alone sensor or with a remote Interface Module.

The sensor can be set to an analogue
(A) configuration for operation with a digital indicator, PID Controller, or PLC. In addition to providing an analogue output, the sensor may be configured for an alarm relay output (default) or a remote analogue input for adjustment of the sensor’s alarm set-point or emissivity.

Alternatively the sensor can be set to a digital (D) configuration (RS485) for operation with the Interface Module, a PC or a PLC.
The 1/4 DIN Interface Module includes an RS232 connector for interface with the PyroSight PC Software.

The PyroUSB 2.2 Series of infrared pyrometers measures temperatures from 45°C to 2000°C accurately and consistently, with an outstanding response time.

The selectable 0 to 20 mA or 4 to 20 mA output is compatible with almost any indicator, controller, recorder, data logger etc. without the need for special interfacing or signal conditioning.

The PyroUSB Series measures temperatures from -40°C to 1000°C accurately and consistently, with an outstanding response time of 240 ms.

The 4 to 20 mA output is compatible with almost any indicator, controller,recorder, data logger etc. without the need for special interfacing or signal conditioning.

PyroUSB-151 has 15:1 optics making it suitable for most applications. PyroUSB-301 is specially designed for distant targets and has an optical resolution of 30:1. PyroUSB-CF is designed for small targets and measures a spot size of ø5mm at 100mm distance.

The PyroCouple Series is a range ofhigh quality, low cost, compact sensorswhich measure the temperature ofinaccessible or moving objects andmaterials. They measure temperatures from -20°C to 500°C, accurately andconsistently, with an outstandingresponse time of 240 ms.

PyroCouple sensors are available as either two-wire or four-wire units.
Two-wire PyroCouple sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most non-contact temperature measurement applications.

Four-wire PyroCouple sensors transmit the target temperature as a 0-50 mV or thermocouple output (type J, K or T) plus the internal sensor temperature as a 4-20 mA output. This second output can be used to ensure that the sensor is being operated within the correct ambient temperature limits and prevent damage caused by overheating or overcooling. It can also be used to give an approximate indication of the air temperature surrounding the sensor.

- Temperature range: -20°C to 500°C
- Emissivity setting: fixed at 0.95
- Two-wire 4-20 mA output or four-wire voltage/thermocouple output

PyroCouple M sensors are capable of measuring temperatures in the range -20°C to 500°C and are available with either a current, voltage or thermocouple output.

The miniature sensing head measures just 18mm diameter x 45mm. It is made of stainless steel, sealed to IP65, and will operate in ambient temperatures up to +70°C without additional cooling. This makes the PyroCouple M Series ideal for applications where there is only a small amount of room available to mount the sensor or the ambient temperature around the sensing head is higher than normal.
The electronics module measures 98mm x 64mm x 34mm. It is made of die-cast aluminium, sealed to IP65, and will operate in ambient temperatures up to +70°C. It is powered from a 24 VDC (28 VDC max) power source.
The emissivity setting is fixed at 0.95, making the PyroCouple M Series suitable for the majority of applications where the target is made of a non-reflective material such as paper, plastic, rubber, cloth, food etc. or it can be used to measure metals that are painted, anodised or oxidised.

PyroEpsilon sensors transmit the target temperature as a 4-20 mA output and offer a simple solution for most non-contact temperature measurement applications.
The sensor’s emissivity setting can be adjusted from 0.2 to 1.0 to cope with different target materials and is controlled by a 4-20 mA input. This gives the opportunity to adjust the emissivity setting automatically from a programmable logic controller (PLC). Alternatively the emissivity setting can be adjusted manually using the optional PyroTune module. If the 4-20 mA input is left open or short-circuit the emissivity setting defaults to 0.95.

Two-way digital communications via a built-in RS485 Modbus RTU interface enables the user to adjust the emissivity setting; compensate for reflected energy; apply filtering; select maximum, minimum, average or instantaneous readings; and peak or valley hold processing. Up to thirty two sensors can be installed on a single multidrop network.

All PyroBus sensors are fitted with precision Germanium lenses for accurate optics. Model PB21 has 2:1 optics making it suitable for most applications where the sensor can be mounted close to the target. Model PB151 is designed for small or distant targets and has an optical resolution of 15:1. Model PB301 is designed for very small or distant targets and has an optical resolution of 30:1.

These compact sensors are small enough to fit almost anywhere and their rugged stainless steel housings make them ideal for applications where cleanliness and hygiene are paramount.

The VL can measure temperatures from - 40ºC to 700ºC with a response time of just 180ms. It has a narrow 10:1 field of view, and adjustable emissivity so can be configured to measure most materials.

Each unit offers a choice of either 0/4 to 20mA, 0 to 5V or type J or K thermocouple outputs so can be used with virtually all process control instrumentation.

Under the lid of the electronics enclosure are buttons which are used to adjust the configuration parameters of the sensor and set the temperature range, response time and output. From here the analogue outputs can also be configured and maximum/minimum readings switched on or off.

To compliment the analogue outputs the VL also provides a digital relay output, the alarm level and hysteresis of which can be adjusted with the electronics module. The VL also has an RS-485 interface for connection to a PC, and can be
interrogated using the UPP® (Universal Pyrometer Protocol).

The compact sensing head of the VL is made of stainless steel and is sealed to IP65. It can operate in ambient temperatures up to 85ºC without cooling, or 200ºC with air-cooling and purging accessories.
