flow sensors - SS400120

The SFS01 is particularly suitable for low flow velocities up to 3.5 m/s (in gases). It shows very fast measurement results of the flow rate as well as the flow direction. The Silicon Flow Sensor SFS01 offers three main characteristics: — Very fast response time <5 ms — Very low energy consumption — Easy system integration including temperature compensation Well-adapted channel geometries allow the performance of the sensor to be optimally aligned to the desired application. The SFS01 flow sensor is ideally suited for space-limited applications, but can also be easily upgraded to complete ready-to-use systems. Suitable application areas for the SFS01 flow sensor are flow measurements in battery-operated / portable devices, air conditioning technology (HVAC), automation technology as well as process and control engineering.

Areas of Application and Advantages BEDIA CLS 10 stands for special versions of our well-proven CLS 40 series for heavy duty applications. Currently, the BEDIA CLS 10 series includes a variety of sensors, which are compatible replacement parts for level switches from Cooper Standard and Robert Shaw which are obsolete nowadays – and this in well proven BEDIA quality. This also includes sensors with 2 complementary CMOS outputs. It should be emphasized that the water sensors with two complementary outputs can be operated with a supply voltage of 4.75 V DC – 32 V DC. Operating Principle The function of the sensor is based on the capacitive principle. It detects the change in capacitance that arises when an electrode surrounded by air is immersed into a liquid medium. This change in capacitance at the electrode of the sensor excites an oscillator, causing it to oscillate (at a frequency of approx. 600 kHz). Then this signal is processed by a microprocessor-based evaluation circuit.

Conductivity sensor for water Analysis The conductivity sensors of the OPTISENS COND 1200 series have a standardized robust design and a long lifespan. The conductive measurement principle is characterized by high sensitivity, especially at low conductivity values. For this reason, the COND 1200 sensors are perfect for low-contaminated, noncorrosive media such as pure water, steam and cooling water.

EGE compact devices for the flow monitoring of gaseous media contain measuring and amplifier in a single housing. They are used where a visualisation of the flow rate on site is required. EGE flow sensors for gaseous media feature two pins which contain the thermal measuring elements. The sensors are set up directly at the device. EGE sensors for gaseous media are characterised by a rapid response capability and reliable operation. Based on the principle, there are no moving parts in the air flow monitors and they can, therefore, also be used in aggressive environments. Devices for air conditioning technology have smooth measuring surfaces and need not protrude far into the flow duct.
