• Q1: What Focusens need to match right sensor and send quotation soon?
  • A:

    1.       Drawing of the sensor part you are in need. (Most convenient and prefered if you have it)

    2.       A sensor probe generally consist of 4 below basic parts, it will works if you can describe us your specific  requirements on below :

    -          Your requirement on parameter or electrical value of sensing element

    -          Material and size of probe/ sensor house

    -          Gauge and size of extension cable

    -          Requirements on other accessories like connector, cable gland, label, etc

    3.       A sample of existing sensor that you want to order same. ( we measure sample and send counterpart )

    4.       In case you are not able to specify above and your project is open for sensor selection, we can make recommend base on your exact field application requirement.

  • Q2: What is typical phase for set up a sensor project with Focusens ?
  • A:

    Our customers sensor projects are customized sensors for majority cases , that means our sensor projects growth with customers projects from design evaluation to mass supply. A typical flow of sensor project with Focusens is like below:

    Specification agreement Sample TestTrial OrderMass supply

  • Q3: NTC Thermistor FAQs
  • A:

    Q: How responsive is NTC?

    A: Response time is defined as the time it takes to reach 62% or a new temperature and is a function of mass. The smaller the sensor, the faster the response. Typical response time of NTC thermistor sensors is < 15 seconds.

    Q: How stable is the NTC sensor?

    A: Different sensor families have different stability ratings. Epoxy coated NTCs are less stable than sealed glass NTC sensors.

    Q: How do I choose a resistor value for my application?

    A: In general, use low resistance sensors for low temperature applications and high resistance sensors for high temperature applications. The goal is to have an operating resistance value within the temperature range you are interested in.

    Q: Can NTC be used for cryogenic applications?

    A: Yes, but at -200°C the accuracy is based on mathematical modeling.

    Q: What is the difference between a thermistor and an RTD?

    A: Each technique has its pros and cons, and which technique is best for a particular application will depend on a number of factors, including temperature range, desired accuracy, time response, cost, and many others.

  • Q4: What is your payment term ?
  • A:

    100% prepayment for orders amount below 5000USD. 

    For order amount above 5000 USD , we requires 30% prepayment and balance payment made before shipment . 

  • Q5: What is usual way of shipment ?
  • A:

    Generally our sensor components have small volume, 60% of our goods are shipped by courier DHL Fedex TNT etc. We can use our courier account , we can also use receiver courier account according to request.

    For big volume shipments, there are options by air , by sea or by train like China-Europe Railway Express.  

  • Q6: Why Focusens ?
