Measure temperatures up to 1000°C with non-contact PyroMiniBus sensors

PyroMiniBus non-contact infrared sensors measure temperatures from -20°C to 1000°C and provide an RS485 Modbus RTU interface. The sensors are capable of being used in ambient temperatures up to 120°C without cooling. They may be connected directly to third-party Modbus Masters, and they are compatible with the optional PM180 6-channel touch screen interface, which provides temperature display, data logging, alarms and analogue outputs. A 6-channel junction box (model PMBHUB) is available to easily connect PyroMiniBus sensors to the PM180 as a complete temperature measurement system.

PyroMiniBus sensors are designed to measure the surface temperature of non-reflective materials in industrial applications, from -20°C to 1000°C.

Sensors have direct RS485 Modbus communications, allowing them to be connected directly to third-party Modbus hardware.

They are sealed to IP65, built from 316 stainless steel, and fully tested to industrial EMC standards.

They can measure food, paper, thick plastics, asphalt, paint, bulk materials and organic materials, as well as most dirty, rusty or oily surfaces.

Robust

PyroMiniBus sensors have an operating temperature rating of up to 120°C with no need for cooling.

Compact

The sensors measure just 45 mm long (plus cable gland), so they can fit into the smallest of spaces.

Configuration

Up to 6 sensors can be connected to the optional PM180 interface module, which provides temperature display, configuration, and high-capacity data logging to a MicroSD Card.

Analogue and relay outputs are available via separate DIN rail mounted modules.

Low Cost

With up to 6 sensors connected to one PM180, the PyroMiniBus is an ideal low-cost non-contact temperature measurement system.

Networkable

PyroMiniBus sensors and PM180 sub-networks may be connected directly to an RS485 Modbus SCADA system or PLC. It is possible to measure the temperature of hundreds of locations on the same network.

Typical Applications

The PyroMiniBus may be installed as a new temperature monitoring system, or integrated into an existing Modbus network with third-party hardware.

With two Modbus interfaces, the PM180 touch screen module makes an ideal local display for a group of sensors as part of a larger system.

The PMBHUB junction box makes it easy to connect the system together.

Never miss a critical temperature event. In condition monitoring applications, the PyroMiniBus system is an always-on solution that can replace manual checks with a handheld thermometer or expensive thermal imager.

For example, some typical uses include:

Power Distribution

Monitor the temperature of busbar joints in switchgear cabinets. Hundreds or even thousands of points can be monitored on the same network using PyroMiniBus sensors.

Curing Ovens

Fibreglass impregnated with epoxy is cured in an oven to increase strength. PyroMiniBus sensors are placed inside the oven at up to 120°C, to build up a temperature profile at many points on the entire surface of the workpiece, and to communicate the measured temperature to the heating system that controls the hot air blowers in the oven. Industries include boatbuilding and aerospace as well as many others.

Industrial Bakery

Check the temperature profile of bakery products at multiple points along a conveyor oven.

Corrugated board manufacturing

Monitor the web temperature along an entire corrugator, with local displays for each section of the production line, and centralised monitoring in the control room. Sensors withstand 120°C, and can be used in high-temperature areas such as single facers without cooling.

Automotive

A large system of PyroMiniBus sensors can monitor the paint curing process at several points.
Monitor temperatures around the entire vehicle in environmental test chambers.

Condition Monitoring

A network of PyroMiniBus sensors can monitor all the bearing temperatures on a machine, a runout table, or the whole factory. The PyroMiniBus is ideal for measuring the temperature of all painted metal surfaces.

Infrared Curing

Arrays of sensors fitted on a rig of infrared curing lamps ensure an even temperature profile along the part being cured. Surface coatings, paint and epoxy are ideal target materials, among many others.

Gas Cylinder Filling

Monitor temperatures to improve repeatability in the filled volume and improve filling efficiency. The temperature of every cylinder on a filling rig is easily monitored with no need to manually move contact probes.
