FineTek SA27 Operation Manual

SA27(SAX10□7C)Capacitance Level Switch
Operation Manual
※ When there are materials or mixtures with multiple characteristics such as high/low dielectric and
conductive haracteristics simultaneously (for example; silica sand in the glass industry, etc), it must be
tested on the site first, to etermine whether the sensor is suitable or not. If there still exists measuring
problems, we suggest using our uning Fork Level Switch (SC) or Rotary Paddle Level Switch (SE).

SPECIAL CONDITIONS FOR SAFE USE OF PRODUCTS
1.The user should contact the manufacturer directly if detailed information regarding the product is
required.
2.If the product sensor bar is made of or coated with non-metallic materials, specific measures should
be taken to prevent the danger of static electrical explosion.
PRECAUTIONS FOR RRODUCT USE
1. The safety parameters of the electrostatic capacitance level
switch are listed below：
●
Power supply : maximum voltage Um : 250V
●
Supply voltage / Contact rating :
110~220Vac±10% ,24Vdc±20%
● Power consumption : 2W
● Contact output : maximum voltage Um : 250V
● Relay (SPDT) : 5A / 250 Vac, 5A /28 Vdc
● Transistor (three-wire PNP or NPN) : 400mA/24Vdc±20%
Transistor (four-wire PNP or NPN) : 400mA/60Vdc
●
2. Open the product only after the power supply is cut off.
3. The cable entry port must be equipped with a cable entry device or a plug. The component must be
explosion-proof certified according to GB3836.1-2010(IEC 60079-0:2007),andGB3836.2-2010(IEC
60079-1:2007) The explosion-proof type is IIC Gb or Ex db IIC, and connection type is 1/2NPT. The
minimum number of clamps is 6. The installation and use of the cable entry device or the plugging
device must comply with the requirements as stated in the instruction manual. Ensure that the
cover's protection level reaches IP65, and that it meets the requirements of GB4208-2008(IEC
60529:2001) standard.
4. The user should keep the product's surface cover clean to prevent dust from accumulating. Do not
use methods such as blowing with compressed air to prevent dust clouds from raising and forming.
5. The user should not replace the product parts by himself. Contact the product manufacturer to
resolve any operational problems and prevent damage.
6. The relation between the temperature group and medium temperature range is as follows (refer to
Figure 1).
7. Installation, use and maintenance of the product should comply with the instructions found in the
product manual and the following standards:
–
GB3836.13-1997(IEC60079-19:1993) "Electrical Equipment for Explosive Gaseous Atmosphere
Part 13: Repair of Electrical Equipment for Explosive Air Pressure".
–
