New small temperature sensor

Louise Smyth

RS Components has launched a new RS Pro infrared temperature sensor. Key features of the device include its extremely small size – 31mm diameter by only 30mm high – and side-entry cable, making it ideal for mounting in areas were space is limited. Other features include fast 125ms response time, built-in temperature display and controls.

The device is essentially a non-contact thermometer that is designed to measure temperature from a distance. Infrared thermometers are typically
used for a wide variety of temperature monitoring functions, primarily in applications where contact sensors are unsuitable, such as when the target object is moving or inaccessible, or when a fast response time is required. Use of the sensor’s analogue voltage output enables the setting of alarms, or connection to a data logger for quality checking.

Although the unit is similar in operation to handheld temperature measurement guns, the RS Pro device is intended as a permenant measurement unit for fixed mounting via a bracket, for example to instal on manufacturing machinery to measure product temperature, or to monitor the condition of machine parts. Key industrial application examples include: product temperature measurement in paper and cardboard manufacturing, food manufacturing, pharmaceuticals, thermoforming, curing and drying, as well as condition monitoring on mechanical or electrical equipment.

The unit features two simultaneous and configurable outputs: selectable voltage-output ranges from 0 to 5V, 1 to 5V or 0 to 10V DC, proving a
linear voltage output with measured temperature; and an open collector alarm output for temperature threshold and hysteresis. Other features of
the sensor include temperature measurement from 0 to +1000°C; accuracy of ±1.5% of reading or ±1.5°C; IP65 protection, and operation over the
ambient temperature range from 0 to +70°C.
