See Four New Cutting-Edge IR Temperature Sensors at the Machine Building Show

Calex Electronics, the world renowned British manufacturer of power converters and infrared temperature sensors, will be demonstrating several exciting new product ranges at the Machine Building Exhibition.

With more than 50 years’ experience in measurement and control, Calex is able to combine detailed application knowledge with a keen understanding of cutting edge technology to produce what is arguably the most innovative range of IR temperature sensors in the world.

Here are some brief details about just four of the new sensors you can see on their stand:

1. New Smartphone Configurable Infrared Temperature Sensor.

The PyroNFC is an advanced non-contact infrared temperature sensor with voltage and alarm outputs, plus wireless NFC communications, all of which can be used simultaneously.

It measures from 0°C to 1000°C, accurately and repeatably, with a fast response time of 125 ms. It is sealed to IP65 and will operate in ambient temperatures up to 85°C without cooling, so it can withstand harsh environments.

Simply touch an installed sensor with a smartphone or NFC device and read the temperature continuously using the free-to-download Android app.

Use the app to instantly save configuration settings to sensors with no need to connect them to anything – not even the power supply!

Configurable settings include temperature range, linear voltage output type and scale, alarm output threshold and hysteresis, averaging period, emissivity setting, reflected temperature compensation and peak or valley hold processing.

The PyroNFC is extremely small, making it ideal for mounting in tight spaces. It measures just 31 mm diameter by 29 mm long. The form factor, with side-entry cable, is perfect for brake testing applications, plus many others.


2. IR Temperature Sensor with Lightning Fast Response Time, Tiny Measurement Spot and Continuous LED Sighting.

With its amazing 0.001 second response time, the PyroCube is the fastest IR temperature sensor in the world. Combine this speed with an ability to measure targets as small as 1.6 mm diameter and you have a sensor that can measure rapidly moving and small objects on almost any modern production line.

The continuous LED sighting shows exactly where the PyroCube is aimed and indicates the precise size of the measurement spot while readings are being taken.

It can measure temperatures in the range 0°C to 500°C, and has a current or voltage analogue output and choice of alarm outputs.

The optional multilingual touch screen interface can be used for temperature display, data logging, sensor configuration and alarms.

The large, bright backlit temperature display is visible from a distance and turns red in an alarm condition. You can also see a graph of the measured temperature and log more than a year of data to a single MicroSD Card. All the sensor’s configuration settings can be adjusted via the intuitive touch screen interface.


3. Fibre Optic Pyrometer for Harsh Applications

The FibreMini infrared sensor is designed for measuring high temperatures from 250°C to 2000°C.

Its miniature sensing head withstands 200°C ambient temperature and is sealed to IP65. It measures just 12 mm diameter by 48 mm long and contains no electronics, which makes it ideal for use near induction heaters and strong electromagnetic fields.

The FibreMini measures temperature over the spectral range 2.0 to 2.6 µm for improved accuracy on metals. It has built-in laser sighting which can be used while the measurement is taken, allowing the user to see the precise location and size of the measurement spot during operation.

The touch screen display offers advanced configuration, signal processing and data logging capabilities. There is a choice of analogue or digital output and alarm relays on all models.


4. Multi-Channel Infrared Temperature Monitoring System

The PyroMiniBus is an industrial infrared temperature monitoring system, with miniature sensing heads and optional display modules.

PyroMiniBus sensors are designed to measure the surface temperature of non-reflective materials in industrial applications, from -20°C to 1000°C. They are sealed to IP65, built from 316 stainless steel, and fully tested to industrial EMC standards.

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

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

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.

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

To measure more than 6 locations, PyroMiniBus sensors and PM180 sub-networks may be connected to an RS485 Modbus SCADA system or PLC. It is possible to measure the temperature of hundreds or thousands of locations on the same network.
