Pirómetro duas partes para fins de metais de alta temperatura (100 ° C a 2000 ° C)
Modelos PT: 100°C a 400°C

Modelos MT: 250°C a 1000°C
Modelos HT: 450°C a 2000°C

A série PyroMini 2.2 é uma gama de sensores de temperatura infravermelha sem contato com curto-comprimento de onda com módulos eletrônicos separados.

Todos os modelos usam um curto comprimento de onda de medição para maior precisão e tolerância melhorada de obstruções óticas ou erros na configuração de emissividade, do que sensores de comprimento de onda longo.

A exibição de tela sensível ao toque opcional no módulo eletrônico fornece indicação de temperatura, alarmes, configuração e registro de dados no cartão MicroSD.

Uma escolha de óptica está disponível para a medição precisa de alvos pequenos ou grandes a distâncias curtas ou longas, e há uma escolha de 4-20 mA, RS485 Modbus e saídas de relés de alarme.

Field of View Diagrams

Please note: The given measured spot diameter contains 90% of the energy detected by the sensor. For maximum accuracy, we normally recommend the target is at least twice as large as the given measured spot. The sensor may be used at longer distances than shown above. In clean air there is no maximum measurement distance, and the distance does not affect the sensor's measurement accuracy; this is because the sensor is filtered to detect only the wavelengths of IR that are not absorbed by the atmosphere.

Electromagnetic Compatibility Standards

The PyroMini 2.2 series conforms to EMC Directive EN61326-1:2006 (Electrical equipment for measurement, control and laboratory use – Industrial) as well as industrial standards for electromagnetic immunity and emissions.

Electrical Installation

Dimensions (mm)

PM180 6-Channel Hub

6-channel touch screen hub for temperature display, alarms, configuration and data logging, compatible with PyroMini Modbus models, PyroMiniBus and PyroBus sensors. Isolated RS485 Modbus master and slave interfaces allow multiple hubs to be connected to a larger network. Optional modules provide analogue and relay outputs.

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.

Laser Sighting Tool

The Laser Sighting Tool screws onto the front of the sensor during installation and shows precisely where the sensor is aiming. Once the sensor has been aimed at the centre of the target and locked in position, the Laser Sighting Tool can be removed. The laser is operated via a latching push button on the front of the tool.

Dual Laser Sighting Bracket

The Dual Laser Sighting Bracket is a sturdy mount for the sensor and provides continuous target sighting while measurements are being taken. Two parallel lasers indicate the centre of the measured spot and are controlled by a remote switch on the electronics module.

Protective Plastic Window

When fitted over the lens of the sensor, the protective plastic window in stainless steel holder provides mechanical protection and helps retain fragments of lens in case of damage. Adjust the sensor’s emissivity setting to compensate for the presence of the window for maximum accuracy. This accessory is ideal for the food and pharmaceutical industries.

PID Controllers and Indicators

The 4-20 mA output of PyroMini 2.2 -CB and -CRT models may be connected to any of our indicating controllers for PID control.
