Probe characteristics:

NOVATECH 1231 wear-resistant zirconia probe (oxygen sensor) adopts the latest patented technology in the world. It can be directly inserted into the required measurement work area in high dust, corrosive atmosphere, and high humidity environments, with a measurement accuracy of up to 10-30. The probe has a fast reaction speed, a reaction time of less than 100 milliseconds, strong corrosion resistance, and strong wear resistance.

Scope of application of the probe

The 1231 wear-resistant probe is suitable for measuring the flue gas temperature in the range of 0 ℃ to 900 ℃ at the required measuring point, and the outer protective tube material is wear-resistant alloy steel. Such as various coal burning boilers, high dust kilns, etc.

Specifications and technical parameters:

Model: 1231 wear-resistant heating probe
Dimensions: Can be inserted with a total length of 500 (mm), 750 (mm), and 1000 (mm).
Shell material: wear-resistant alloy steel.
Application flue gas temperature: below 900 ℃.
Temperature control: The probe comes with a heater to maintain a constant temperature of the zirconium head.
Thermocouple: K-type
Heating time: About 15-30 minutes can reach the rated temperature of 700 ℃. (Related to flue gas temperature)
Installation connection: The probe comes with a 1.5 "BSP or NPT thread. The user processes the furnace wall matching flange according to the attached diagram in the user manual.
Reference gas: The gas pump in the instrument supplies approximately 50 ml/minute. Use instrument gas and supply gas through the user provided pressure reducing valve and float flowmeter. The manufacturer provides the PVC connection pipe and sensor end connection head from the float flow meter to the sensor with the transmitter.
Gas connection pipe: PVC pipe with an outer diameter of 1/4 "(6.4mm) and an inner diameter of 4 (mm).
Calibration gas connection: The sensor has an inlet for calibration gas, which is closed by a blind end when not calibrated. During gas calibration, the flow rate should be controlled at around 1000 ml/min. The manufacturer provides a 1/8 "NPT threaded pipe joint that can be connected to PVC pipes.
Zirconium battery life: It can operate continuously for 4-6 years. This depends on the composition and temperature of the flue gas. Intermittent operation can affect the service life, and the heater should be kept running continuously.
Response time: less than 4 seconds.
Filter: stainless steel movable type. The outer diameter of the filter is ¥ 42 (mm).
Outer diameter of probe protection tube: ¥ 42 (mm).
Probe junction box temperature: ＜ 130 ℃
Probe electrical connection: direct plug socket type or aviation plug socket.
Weight: 1.5Kg plus 0.55Kg/100mm in length.
Calibration: After the initial installation system works stably, it needs to be calibrated once.
