The split-type ultrasonic level gauge is known for its safety, cleanliness, high accuracy, long service life, and stable performance. It offers easy installation and maintenance, making it ideal for a wide range of applications, including environments with acids, alkalis, salts, corrosive substances, and high temperatures. This device provides real-time liquid level data, supporting efficient automation in industrial operations.
When installing a split-type ultrasonic level gauge, several key precautions should be taken:
1. Ensure the instrument is properly grounded by connecting the 4-20 mA output or XPS terminal to an earth ground.
2. Protect all wiring and cables with sealed conduits to prevent water ingress.
3. Although the gauge has built-in lightning protection, additional surge protection is recommended in areas prone to frequent lightning strikes.
4. In extreme temperature conditions, consider using thermal insulation or cooling systems around the device to ensure optimal performance.
The installation principle for the split-type ultrasonic level gauge includes:
1. The distance from the probe’s emitting surface to the lowest liquid level must be within the instrument’s measurement range.
2. The distance from the probe to the highest liquid level should exceed the blind zone of the device.
3. The probe’s emitting surface should remain parallel to the liquid surface for accurate readings.
The JZ-ORB capacitive level gauge is designed for continuous level monitoring in various containers, such as tanks, silos, and hoppers, whether they hold liquids or solid particles. It is widely used in industries like oil, chemical, power generation, food processing, water treatment, metallurgy, and cement due to its reliability and ability to operate in harsh environments.
Key technical specifications include:
- Power supply: 12–36 V DC
- Input range: 10–4000 pF
- Output signal: 4–20 mA (two-wire system)
- Accuracy: ±0.5% of full scale
- Load resistance: (Vs - 12) / 0.02, where Vs is the supply voltage
- Temperature effect: 1% per 50°C of full scale
- Power supply variation: up to 0.2%
- Ambient temperature: -20 to +80°C
The sensor probe comes in various forms, depending on the application. It can be rigid or flexible, insulated or bare, and is available in threaded or flanged connection styles. Different types of probes are suitable for conductive or non-conductive media, pressurized or atmospheric containers, and varying temperature ranges.
When selecting or using the JZ-ORB, consider the following:
a) Ensure the instrument is compatible with the process conditions, including temperature, pressure, and material compatibility.
b) The dielectric constant of the medium affects sensitivity. For materials with a dielectric constant below 5 μs/cm, a coaxial sleeve (B type) probe is recommended.
c) Proper grounding is essential, especially for non-conductive containers, which may require a reference electrode.
d) On-site calibration is necessary for accurate measurements.
e) Conductive residues on the probe can cause errors, unlike non-conductive media.
f) For non-conductive media, maintain a stable dielectric constant to avoid measurement inaccuracies.
g) Avoid cutting the insulated electrode unless specified.
h) If the medium exceeds 100°C, inform the manufacturer during ordering.
Proper installation and usage ensure the longevity and accuracy of the level gauges, making them valuable tools in industrial automation systems.
