Ee893 digital co2 sensor module for oem applications

The e+e co2 module ee893 is designed for oem applications and for demanding environment. A multiple point co2 and temperature adjustment procedure leads to excellent co2 measurement accuracy over the entire temperature working range; this is a must for process control and outdoor applications.

The e+e dual wavelength ndir co2 sensing procedure compensates automatically for ageing effects. Ee893 is highly insensitive to pollution and offers outstanding long term stability.

With its small dimensions and electrical connection via contact pins and pads, ee893 is the optimal choice for oem devices such as wireless transmitters, hand-helds or data loggers. The measured data, with a range of up to 10000ppm, is available on the e2 digital interface.

An optional kit facilitates easy configuration and adjustment of the module. The measurement interval can be set according to the application requirements; by this the average current consumption can be reduced to less than 60î¼a for battery-operated devices.

The coolant temperature sensor consists of a negative temperature coefficient thermistor that is very sensitive to temperature changes. When the engine coolant temperature gradually increased, Thermistor resistance will gradually decline, On the contrary increases, when the engine coolant temperature changes, the output voltage of the sensor also changes accordingly.
Engine coolant temperature sensor elongated head contact with the cooling liquid, the temperature of the coolant is detected by the change of the resistance value, and this signal is sent to the ECU,Used to detect the engine coolant temperature. The ECU corrects the fuel injection time and the ignition time after receiving the temperature signal.
The normal use of the coolant temperature sensor is -30 ° C to 120 ° C,The corresponding output voltage is 0.3V ~ 4.7V.When the ECU detects an output voltage signal beyond this range,You can determine the sensor circuit failure.

Car temperature sensor,Respectively, water temperature sensor,Exhaust | intake air temperature sensor,These types of sensors are thermistors with the same characteristics,The temperature coefficient is negative temperature coefficient.The water temperature sensor is mounted on the engine cooling water passage,Its role is to detect the engine cooling water temperature,The water temperature sensor housing is fully enclosed,Use the change of resistance value to detect water temperature.The signal temperature value generated by the water temperature sensor is input to the ECU,ECU according to the cooling water temperature ignition control,Correction fuel injection amount to real-time control of the engine,To ensure the normal operation of the engine under different conditions.
Intake | outlet temperature sensors are installed,Within the housing of the air cleaner box or regulator,The air flow meter or an intake manifold,Used to detect the temperature of the engine inhaled air.As the intake air temperature changes will affect the air density,The hotline, hot film cooling strength and the degree of atomization of the mixture have an impact,Intake air temperature sensor,Provide a signal to correct this effect.
