This barometric pressure temperature sensor is equipped with TDK’s newly launched ICP-10111 barometric pressure sensor, which is based on MEMS capacitor technology to achieve ultra-low power consumption, industry-leading relative accuracy, and temperature offset coefficient.

The Fermion: ICP-10111 barometric pressure temperature sensor can measure the pressure difference with an accuracy of ±1Pa, an accuracy enabling altitude measurement differentials as small as 8.5 cm, less than the height of a single stair step.

The pressure noise can be as low as 0.4Pa, and the read data will be more stable. There is a built-in temperature sensor for air pressure compensation. The ICP-10111 offers a temperature coefficient offset of ±0.5 Pa/°C, more stable for long-term use. The combination of high accuracy, low power, and temperature stability in a small footprint enables higher performance barometric pressure sensing for sports activity identification, mobile indoor/outdoor navigation, and altitude-hold in drones

The FS1012 MEMS mass flow sensor module measures the flow rate using the thermo–transfer (calorimetric) principle. The FS1012 is capable of measuring a gas or liquid medium. The FS1012 offers key advantages over resistor–based flow solutions. The sensor utilizes thermopile sensing, which provides an excellent signal–to–noise ratio. The sensor comprises a “solid” thermal isolation technology and silicon–carbide coating to protect
it from abrasive wear and provides robustness and long–term reliability. In comparison, other sensors typically contain a fragile membrane above an etched cavity for the thermal isolation base. The FS1012 features the sensor fully assembled and wire–bonded out to a 6–pin header. Wetted materials consist of a glass fiber reinforced PA66 resin, epoxy, and silicon carbide.

Applications:

1. Process controls and monitoring
2. Oil and gas leak detection
3. HVAC and air control systems
4. CPAP and respiratory devices
5. Liquid dispensing system

Features:

1. Gas or liquid mediums
2. Robust “solid” isolation technology
3. Resistant to surface contamination
4. No cavity to cause clogging
5. Resistant to vibration and pressure shock
6. Low power application
7. Sensitive at low flow rates and differential pressure levels

Specifications:

1. Fast response: <5ms

Cable Float Switch is a control device for automatic On/Off pumps, motor and magnetic valves. It is also an alarm device at certain pre-determined surface levels. It is suitable for use in non-flammable liquids at 250 volts. In potentially explosive atmospheres (e.g. oil tanks) the Switch can be used in conjunction with (Ex) I-isolator switch units. Due to its large float casing, the float Switch has a buoyancy that guarantees smooth, trouble-free operation under all conditions. The switch has a double chamber and a final remolding finish to make it absolutely hermetic.

Features: 

1. It can test the pressure of the liquid.
2. The float switch is a switch that regulates fluid level in the tank or well etc
3. The float switch is resistant to water(sewage water) it is relatively capable of being used for oil, most acids and alkalis
4. The float switch is not explosion-proof.
