Modular fibre-optic temperature measurement via new Rugged Monitoring R501 (Video)

The Rugged Monitoring portfolio of fibre-optic temperature monitors continues to expand. Their latest addition, the R501 chassis, accepts a range of I/O modules for real-time monitoring of up to 256 fibre-optic and other sensors for measurement of temperature, pressure, AC current, AC voltage, DC current, DC voltage and more. It supports both rack mount and distributed installation.

It has been developed to offer an upgradeable and flexible solution for the changing needs of customers, and a short video presentation on it is below.

The fibre-optic enabled modules and other I/O modules use the Dinrail mount, and can be daisy chained to the central CPU module, communicating over CANBUS/MODBUS. Distributed modules can also be directly connected to a datalogger, for example CAN-Logger, while Rugged Connect is an advanced software package available for data visualisation, configuration and reporting.

Like other Rugged products, the R501 can be used in a wide range of applications. These are not limited to Aviation, Automotive, Cryogenic, Battery Bank/Racks, Medical, Semiconductor, Utility, and R&D. It’s wide measuring range (-271 °C to +300 °C), high precision and complete immunity to RFI, EMI, microwave radiation, and high voltages make it an obvious choice for temperature measurement in extreme conditions.

From near absolute to over one thousand degrees – Lake Shore have a sensor to suit

With the UK’s record breaking hot weather continuing, we thought you might like to know that Lake Shore Cryotronics offer four types of sensor for temperature measurement:

Diodes
A diode temperature sensor is the general name for a class of semiconductor temperature sensors. They are based on the temperature dependence of the forward voltage drop across a p-n junction. The voltage change with temperature depends on the material. The most common is Silicon, but Gallium Arsenide (GaAs) and Gallium Aluminium Arsenide (GaAlAs) are also used.

Resistors
These sensors are based on the change of resistance with temperature, and can be classified as positive temperature coefficient (PTC) or negative temperature coefficient (NTC). Platinum RTDs are the best example of PTC resistance sensors.

Capacitors
Capacitors are also used for low temperatures, but usually not for temperature measurement. Capacitance temperature sensors have the advantage of being insensitive to magnetic fields, but they commonly experience calibration shifts after thermal cycling.

Thermocouples
Thermocouples are only useful where differential temperature measurements or low mass are the main consideration. They must be calibrated in-situ as the entire length of the wire contributes to the output voltage if it traverses a temperature gradient.

Each type sensor has its own particular advantages in terms of temperature range and response, as well as design features and drawbacks, so Elliot Scientific recommends contacting us to discuss your application and its requirements.

Lake Shore also do some nice instruments to go with their sensors!

The NOMAD-Touch temperature measurement system is a hot performer from Neoptix

NOMAD-Touch: A single-channel fibre-optic thermometer offers impressive versatility from a rechargeable touchscreen device. This single-channel fibre-optic thermometer allows you to freely move from one area to another to measure temperatures at various critical sensing points in medical, microwave, radio frequency, high voltage, aerospace and military applications.

NOMAD-Touch™ is perfect wherever you need immunity to electromagnetic fields, where conventional metallic sensors cannot be used. Please contact us for more information.

 


Lake Shore’s temperature sensor data is now online

Lake Shore is now offering all their temperature sensor information in one convenient online page. The new Sensors’ page contains links to:

  • Datasheets
  • Installation instructions
  • Application notes
  • Catalogue pages

Lake Shore logoOver the coming months, Lake Shore will migrate away from shipping calibration data CDs with calibrated sensors and will instead only offer this data via a portal accessible from the new page.

Data is currently available online for sensors shipped since the beginning of 2016, so if an existing CD is lost or damaged, the calibration data can be quickly downloaded providing you have the serial number of the relevant sensor on hand. Alternatively, contact Lake Shore Service for archived curves.

Lake Shore space-qualified sensors were on the hugely successful Cassini Huygens mission to Saturn that ended earlier this month.

Nearly twenty years of gathering temperature information in an extreme environment is a good advert for their sensors, and Elliot Scientific often supplies them to the aerospace industry and space scientists in the UK and Ireland.

Please contact us for more information.
