Detailed information on the German MESA oxygen probe heating power supply:

NTV44P is a specially designed heating power supply from MESA company, which can control the operating temperature of the Lambda probe at a fixed value. Therefore, errors caused by different gas cooling and environmental temperature changes can be fully compensated. In addition, its initial heating is much faster than the fixed voltage mode. It can be said that the new NTV44P heating power supply is a smart device completely managed by a microprocessor. The important function of this device now is to convert the voltage signal of the Lambda probe into an equivalent isolation signal of the zirconia probe, so that Lambda probes with higher efficiency, lower cost, and longer lifespan can be applied to existing control systems.

There are several types of NTV44P:
Regular Type: NTV44P Basic
The functions include:
1. Lambda probe signal input;
2. Control the operating temperature of the Lambda probe;
3. Non isolated analog signal output 0-1300mV

Intelligent Type: NTV44P Advanced
The functions include:
1. Lambda probe or oxygen probe signal input;
2. Control the operating temperature of the Lambda probe;
3. Isolate thermocouple input;
4. Isolation output module 0-1300mV or 0-10V or 0-20mA or 4-20mA
5. It can calculate the percentage of oxygen content or dew point, and convert between lambda probe and oxygen probe;
6. Two point calibration mechanism;
7. Four blowing modes: fixed time blowing, fixed temperature blowing, fixed mV value blowing, manual input data blowing

In addition, users need to configure the T300 handheld terminal to configure and set parameters for all the above functions.
