Sensors using Thin-Film Technology
Thin-Film Sensors

Thin-Film Technology

Thin-film technology has revolutionized the measurement and sensor industry. In thin-film deposition, a thin layer of metal is deposited, for example, onto a ceramic substrate. This technology allows for the production of extremely small sensors with enhanced operational capabilities such as improved response times, maintaining robustness, and packaging versatility. 

Innovative Sensor Technology (IST) USA Division is a world-class manufacturer of thin-film sensors. IST produces four types of thin-film measurement technology:  RTD temperature sensors, capacitive relative humidity sensors, mass flow sensors, and conductivity sensors.  Manufactured at the component level, these elements are available with a diverse range of standard and custom features.

With our state-of-the-art manufacturing technology, we offer both standard and custom sensors to satisfy various applications. Our sensors cover requirements for system integrators in the process control, building automation, test & measurement, medical, automotive, and appliance industries.

Our Sensors

Our four categories of thin-film measurement technology include temperature, humidity, flow and conductivity. Here is an overview of each of those product categories:

  • Temperature
    IST offers RTD temperature sensors in both platinum and nickel. The sensors are designed with the highest quality materials, allowing them to operate over a temperature range of -200°C to +1000 °C for platinum and -60°C to +300°C for nickel. The TSic is offered as a calibrated temperature sensor with an integrated signal converter for analog or digital output. It is easy to integrate and offers excellent accuracy with long term stability.

  • Humidity
    IST thin-film capacitive relative humidity sensors are capable of measuring 0 to 100% relative humidity and operating at temperature ranges of -80°C to +190°C.  The humidity sensor product line features sensors with excellent linearity, low hysteresis, fast response times, and high chemical resistance.

  • Flow
    IST thin-film mass flow sensors offer solutions for a wide variety of flow applications.  The thin-film and membrane technologies incorporate highly accurate temperature sensors and heaters as core elements of the sensors. IST flow sensors are applicable in both gas and partially in liquid.

  • Conductivity
    With thin-film technology, the IST conductivity sensors operate in temperatures from 0°C to +90°C. The temperature sensor on the element offers temperature compensation and is placed directly at the measurement point for assured accuracy.  The basic construction of the conductivity sensor makes it resistant to various chemicals.


Our wide product range is the choice of many renowned end customers and OEMs in the following fields. While our products are widely used in these industries, they are by no means limited to them:

  • Building Automation
    The Heating Ventilation and Air-condition (HVAC) market in the Building Automation industry focuses on controlling atmospheric conditions to make them more suitable. IST’s thin-film platinum and nickel temperature sensors are ideal for heat meter monitoring and control applications in HVAC because of their high resolution and long term accuracy.
  • Appliances
    Measurement and control is an essential element in the success of products in the consumer appliance industry. Precise temperature measurement in cooking equipment along with flow control in cleaning equipment are crucial to the proper functioning of different appliances. IST’s sensors are more than capable of meeting the needs of products in the appliance industry. Applications include oven controls, dewer humidity controls, vacuum flow, and smoke detectors.
  • Medical
    The medical industry requires the accurate and consistent performance of its equipment. IST’s precise and reliable sensors meet the needs of these applications. Applications include incubators, respirators, spirometers, dosing monitors, and oxygen meters.
  • Test & Measurement
    Test and measurement is an industry in which highly accurate and stable sensors are crucial. IST’s full line of sensors has applications for this industry. Our sensors can be directly integrated into instruments including assemblies, probes, meters, and more.
  • Process Control
    Measurement and control is an essential element in determining the effectiveness of products in the Process Control industry. A wide variety of applications are met in this industry by IST’s diverse family of sensors, including discharge air monitoring, and gas and liquid flow control.
  • Automotive
    With new innovations in the automotive industry, the need for accurate and robust measurement methods has become relevant. IST’s sensing solutions satisfy this need. Applications include exhaust gas temperature, engine temperature, windshield fogging, in-cabin comfort, and engine coolant flow.
