By Principles


BriskHeat offers 50 years of experience in flexible heating solutions; they pioneered the use of resistance fabric heater technology  for semiconductor grade heating solutions: gas abatement, and liquid and gas transfer lines. BriskHeat has Class 10 capability and uniform watt control offering the best in class thermal solutions.

Our custom researched thermal management solutions, will be bench tested and thermal profiled to your system requirement in full dynamic configuration. 

Our technology offers thermal management to elevated temperatures of 600°C (unsuitable for precise control in extruded silicon jacketing).

BriskHeat offers uniform temperature control of small gasline (>1/2")and flow structures through an implementation of inner liner of aluminized foil creating thermal diffusion effect that supercedes conductive heat transfer heating alone.

BriskHeat as well builds Hot Bonder for fabrication repair in carbon composition structures.

Let us see what we can heat and insulate for you.

18 years experience...

EI Sensor

Full line of temperature components - RTD, NTC thermistors and probe design.

Process Sensing 

PST specializes in the process sensing of on line and sample systems em to detect trace and percent moisture and Oxygen - from PPB (parts per billion) to recent from .5% - 100%

One of the critical determinant of semiconductor manufacturing today.

We offer inline systems, sample systems calibration systems and all course of methods for detection NIST traceable trace detections and percent determination of moisture and oxygen in gas streams.

Piezo sensors in PDVF and Coploymer. Custom design, implementation, and manufacture of piezo materials.
Experience in all phases and types of piezo sensors for hydrophones, sleep, tamper and vernal use in sheet and cable form factors.


Capacitec offers sensor technology advancing the capacitive principle of measurement physics to  displacement measurement design.


Our customers seek precision movement detectors, part-dimensional sizing, thin gap measures, planar and parallelism metrics.

Capacitec supports markets where a more sophisticated ruler is required and in areas where traditional sensors cannot fit or survive the environment. Capacitive sensor survive in severe environments of high temperature, magnetic fields, high radiation and vacuum.

Offering performance into the manometric range on sensing precision under static and dynamic (DC to >32 kHz). OEM sensors for the most demanding displacement sensing applications. Specializing in semiconductor manufacturing equipment of wafter and flat parallelism.

We offer a line of Bluetooth wafer and gap sensing instruments to align, parallelize and reference metrics for system dynamics in vacuumed processing chamber. We have come the standard in gap high demanding gap applications in aerospace, semiconductor and metrology. We offer definitive gap measure technology for the planet.

27 years experience...


Measurement specializes in custom fabricated pressure sensors. They have engineering staff to design and manufacture to order - primarily isolated pressure devices in mems structures and solid front for consumer, industrial and semiconductor clientele.

Full line of environmental Sensors specializing in  VOC, RH and flow components
