Nernst1238High temperature jet zirconia probe(Oxygen sensor) adoptsIn high-temperature environments, highly corrosive atmospheres, and high humidity environments, it can be directly inserted into the required measurement work area with a measurement accuracy of up to 10%-30to100%. The temperature ranges from room temperature to 1200 ℃, and the probe has a fast reaction speed with a reaction time of less than 100 milliseconds.

Nernst 1238High temperature jet zirconia probe,Suitable for measuring the flue gas temperature at the required measurement pointWithin the temperature range of 0 ℃ to 1200 ℃, the outer protective tube material is high-temperature alloy steel. Such as various metallurgical heating furnaces, stepper heating furnaces, energy storage heating furnaces, stainless steel bright annealing furnaces, ceramic tunnel sintering furnaces, etc.

Specifications and technical parameters:

Model:1238 high temperature jet type

Size:The total insertable length is500（ mm）,750（ mm）, 1000 （mm）。

Shell material:wear-resisting alloy steel.

Application flue gas temperature:Below 0 ℃~1200 ℃. The application site requires compressed air.

Temperature control:The probe comes with a built-in heater to maintain a constant temperature of the zirconium head.

Thermocouple:K-type

Heating time:aboutIt takes 15-30 minutes to reach the rated temperature of 700 ℃.

Installation connection:The probe comes with its own1.5″BSP， Or NPT thread. The user shall process the furnace wall matching flange according to the attached diagram in the user manual.

Reference gas:The air pump inside the instrument supplies approximately50 ml/minute. Use instrument gas and supply it through the pressure reducing valve and float flowmeter provided by the user. The manufacturer provides PVC connecting pipes and sensor end connectors from the float flowmeter to the sensor along with the transmitter.

Gas connection pipe:The outer diameter is1/4 "(6.4mm) PVC pipe with an inner diameter of 4 (mm).

Verify gas connectionThe sensor has an air inlet that can be used for calibration, and when not calibrated, it is sealed by a stopper. During the calibration process, the flow rate is controlled atAbout 500 ml/minute. The manufacturer provides 1/8 "NPT threaded pipe fittings that can be connected to PVC pipes

Zirconium battery lifespan:Can run continuously4-6 years. This depends on the composition and temperature of the flue gas. Intermittent operation will affect the service life, and the heater should be kept running continuously.

Response time:less than4 seconds.

filter:Stainless steel movable type. Filter outer diameter ￠42 （mm）。

Outer diameter of probe protection tube:￠32 （mm）。

Probe junction box temperature:＜130℃

Probe electrical connection:Direct plug socket type or aviation plug socket.

Weight:1.5Kg plus 0.55Kg per 100mm length.

Calibration:After the initial installation of the system is stable, it needs to be verified once.
