 特性
Sensing Band boasts high degree of chemical resistance. The K7L
can be used in a wide range of applications from semiconductor production
installations to food-processing equipment
|
|
| Inter-electrode Resistance Detection |
 |
| + |
Stable detection of liquids
with impedances of up to 50MWand common water. Four sensing ranges
are available ensuring detection suited to the application. You can
set it to detect, fresh water, pure water, distilled water, plating liquids,
chemical liquids, and IPA (isopropyl alcohol) |
| Noise Canceller Function (Pat.) |
 |
| + |
Incorporates a noise
canceller circuit that uses a 3-conductor cable, ensuring a high level of
noise immunity
|
| AC Detection Method |
 |
| + |
This K7L internally oscillates
AC signals provided to the Sensing Band at approximately 3.75Hz, protecting
the Sensing Band from electric corrosion, and ensuring safe operation
|
| Multiple Installation |
 |
| + |
The power supply circuit
and the detection circuit are isolated and so several Amplifiers can be
installed in the same place
|
| Sensing Band with Excellent Chemical Resistance |
 |
| + |
SUS316 and polyethylene
are used for the Sensing Band's core and sheath respectively ensuring high
resistance to both acidic and alkaline liquids

应用实例
|
|
| Liquid Leakage Detection for Measuring Baths in CMP Devices
|
 |
| + |
Detects liquid leaked
to drain pans, and prevents damage to devices and cleaning irregularities
for waters
|
| Detection of Liquid Leakage at Pipe Joints for Chemical Liquid
Tanks |
 |
| + |
Liquid leakage at a pipe
joint can be detected by wrapping the Sensing Band around the joint
|
| Detection of Condensation and Liquid Leakage at Semiconductor
Production Installations |
 |
| |
Detects condensation
inside cleaning devices and liquid leaked to the surroundings
|
| Detection of Cleaning Fluid Level for Plating Devices
|
 |
| + |
Detects the level of
pure water inside plating baths. High sensitivity allows high-accuracy
control that prevents cleaning irregularities

F03-16 and F03-16PE
Sending Bands are available in 1m, 2m, 5m, 10m, 15m, 20m, 25m, 50m,
75m and 100 m as standard lengths. For example, if a 4-m-long
F03-16 Sensing Band is required, place an order for F03-16 5M (5m in
length). If you need a 12-m-long F03-16 Sensing Band, place an
order for F03-16 15M (15m in length). |
