Temperature Sensors
|

Measurement Principle
Our resistance temperature detectors (RTDs) function on the principal that a
material’s electrical resistance changes with temperature. This positive
resistance-temperature relationship holds true within extreme temperature
ranges over extended periods of time. With knowledge of this relationship,
an accurate measurement of temperature can be derived from the resistance
value of an RTD. Product Overview
IST’s temperature product line includes platinum and nickel RTDs, and
temperature sensor ICs. Platinum and nickel sensors are both resistance
temperature detectors with a variety of temperature ranges, extension types,
and nominal resistances. While platinum can withstand extreme temperatures
from -200°C to +1000°C, nickel has higher resolution within a smaller
temperature range. We also offer custom RTDs in both platinum and nickel
with user specified values for TCR, nominal resistance, etc. TSic sensors
are semiconductor temperature sensors that feature highly accurate
measurement within a limited temperature range. They are ideal for mobile
applications due to their low power consumption.

MultiSens - The universal temperature sensor
Temperature range of -70°C to +250°CThe
problem:
In industrial measurement technology, platinum and nickel thinfilm precision
resistors are now firmly established and are seen as the real industrial
standard. With these conventional temperature sensors, the thermal
characteristics is principally determined by the choice of platinum or
nickel as the basic material together with known technological parameters.
At the end of the manufacturing process, only the absolute value of the
resistor at a fixed temperature can be accurately trimmed with a laser.
Important parameters such as the temperature coefficient of resistance (TCR)
or the coefficients of the higher order are fixed and can no longer be
changed.
The solution:
With the MultiSens universal temperature sensor, we have created a product
which utilizes the advantages of thin-film sensors such as reliability,
accuracy, long-term stability, exchangeability and small size and largely
eliminates the disadvantage of dependence on the thermal characteristic of
the basic material. The principle of this complex thin-film sensor is based
on a multiple number of trimmed resistors with different, well-defined
thermal characteristics which are connected in a network. A special computer
program calculates the individual nominal values of the individual resistors
which are then accurately aligned by laser trimming during the manufacturing
process. Thanks to this technology, a very broad band of sensor
characteristics can be covered.

Humidity Sensors
|
 |
Measurement Principle
Capacitive RH sensors consist of a ceramic substrate on which a thin film of
polymer is deposited between two conductive electrodes.
The sensing surface is coated with a micropourous metal electrode, allowing
the polymer to absorb moisture while protecting it from contamination and
exposure to condensation. As the polymer absorbs water, the dielectric
constant changes incrementally and is nearly directly proportional to the
relative humidity of the surrounding environment. Thus, by monitoring the
change in capacitance, relative humidity can be derived. Product
Overview
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.

different layouts and connections such as SMD and wired configurations are

Flow Sensors
|
 |
Measurement Principle
Thermal mass flow sensors utilize heat transfer principles to determine the
flow velocity of a fluid. As fluid passes across the sensor, heat is carried
from the sensor to the medium. This relationship is dependent upon the flow
rate. As flow increases, so does the amount of heat that is transferred. By
knowing the temperature of the medium, the flow rate can be determined from
the amount of voltage compensation needed to maintain a constant temperature
differential. Product Overview
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, have an
operating temperature range of -30°C to +450°C, and can measure flow rate
and direction from 0.0001m/s (microflowSens) to 100m/s (respectively from
1mL/min to 10L/min). In addition to measuring flow rates, our liquid
sensors can detect the presence of a liquid, biofilm, or bubbles, as well as
indicate liquid level .
Development channels guarantee the best possible adaptation of our sensors
to the requirements of your application, whether in terms of dynamic range,
response time, directional detection or ambient conditions. Connecting
options such as different wires, solutions on flexible substrates or
injection-molded encapsulations are available (denoted by letter A).

Gas flow sensors
FS Series
The FS Series, based on the principle of the hot-film anemometer, is
suitable for a wide range of different applications, with the tried and
tested thin-film technology guaranteeing ultimate reproducibility and long
service life.
Essentially, the FS5 Sensors consist of a heater and a temperature sensor.
The heater is heated up when voltage is applied. A flow causes it to cool
down, and the drop in the heater's resistance is measured. The configuration
of the heater and of the temperature sensor in the FS5 is such that a
measuring range of up to 100m/s in gases and a measuring range of up to
10m/s in liquids can be covered. The low mass of the sensor results in rapid
response times and short temperature ramp-up tmes. The temperature range in
use reaches from -30°C to +150°C. The element is available with a plastic
holding fixture, allowing the sensor to be installed easily in
customer-specific enclosures. be handled

Liquid flow sensors
Thermal Mass Flow Sensor for all-purpose use in Liquids
The Flow Sens is the result of continuous development of IST AG quality
products. The layout of the Sensor that is optimised for measurements in
liquids consists of two temperature depending platinum resistors, both
deposited on one chip. The low-ohm resistor with a small area is used as a
heater, whereas the other high-ohm resistor serves to measure the reference
temperature. Using a bridge circuit, the differing resistance value of two
elements leads to different (self) heating. The (self) heating is dependent
upon the applied voltage, the mass flow, and the media in which the sensor
is located. Higher voltage increases self heating, a
higher flow rate increases cooling. If the self heating is kept constantly
by a suitable controller, the voltage increases with higher flow rates and
therefore becomes a measure for the mass flow. As a result of his little
thermal mass, this sensor has fast heating and cooling response times. The
measuring principle of the sensor can be used for large operation ranges.
The Flow Sens is also available with a plastic housing of diameter 6mm. This
option provides the user with ideal opportunities to incorporate the element
into custom-built applications or specific housings, e.g. into a T-piece.
