Cowboy with Case

MEET OUR PRODUCTS!

Sigma Sensors introduces its’ Lab Series Calibration wafers to address the challenges presented to semiconductor fabs, metrology departments, laboratories, universities and other learning institutes.

Sigma Sensors’ products and technologies are designed with the customer in mind: ease of use, accuracy, durability, mobility and quality.

Our systems are based on the COWBOY WAFER®, a highly resilient sandwich-type construction composed of two layers of Si wafer with embedded PT100 4-wire thin-film temperature sensors.

The wafer has a shatter-free option and has a survival rate of >50% on the 1M drop test. It comes embedded in a steel/aluminum carrier for ease of handling and added protection during transport. 

Wafers can be purchase freestanding for use with any meter – or as a complete, self-contained system. All the materials are cleanroom safe, non-particle shedding, no outgassing and temperature resistant from -60°C to +200°C.

Every wafer shipped meets the advertised factory specification. As for upgrades, we do offer both traceable, non-accredited calibration as well as ISO17025:2017 accredited calibration.

K2 Calibration Wafer

The TekSense K2 calibration wafer is the highest accuracy temperature wafer available on the market and offers an accuracy of 0.1K in the temperature range from -40 °C to +175 °C. It comes in 200/300 mm and has 13/17 sensors, respectively. It offers optional upgrade paths to -60 °C and +200 °C and can be purchased either freestanding or as a complete system.

From $13,080.00

K1 Service Wafer

The TekSense K1 service wafer offers high reliability. It has been calibrated at 5 temperature calibration points and offers superior performance to currently available and established temperature wafers. It does offer a limited upgrade path to 175 °C and comes in 200mm and 300mm and a selection of 9 and 13 sensors. It can be purchased either freestanding or as a complete system. It also offers an accuracy of 0.5K.

Cowboy Classic - temperature verification wafer

TekSense Cowboy Classic service wafer is the entry model wafer. Regardless of being an entry-level product, it still surpasses our competitors’ products in all technical specifications. It can be purchased either freestanding or as a complete system.

The base models offer 5 and 7 sensors on the 200mm configuration and 7 and 9 sensors on the 300mm wafers. The standard accuracy is <0.2K, and the base temperature range is 0 °C to 140 °C with optional upgrades to -40 °C and 150 °C, respectively. This wafer is sold as a complete system only.

PT100 THIN-FILM SENSORS

We offer standard spec, batched, custom harnessed as well as calibrated PT100 and PT1000 sensors in both 2 wire and 4 wire configuration for sale. Calibrated sensors have inherently improved accuracy specifications over DIN spec sensors, as seen in the graph. The colored graphs depict the accuracy range as per class specification. Our standard range for sensors is -40 °C to +200 °C. Cold capability is offered to -80 °C and hot to +260 °C.

At 200 degrees Celsius these range from ±0.5 °C to ±2.5 °C compared to a calibrated sensor whose accuracy can be as low as ±0.03K k=2. This makes a SIGMA K2 sensor the sensor of choice when accuracy and traceability counts.
