CAPTRON stands for high-quality, innovative sensor
technology products. The focus of development and production
is on capacitive sensors for use primarily in automation and
trafc engineering.
Beyond the standard programme, CAPTRON is a specialist for
individual customer and application solutions.
CAPTRON Elektronik GmbH was founded by Reinhard Bellm
in Munich in 1983. Initially, the company focused on capacitive
level measurement. Since 1992, optical sensors have been
added to the product portfolio. In 1994, capacitive
SENSORswitches for industry and trafc engineering were
added - one of the main business elds of CAPTRON since then.
More than 30 years of experience make CAPTRON one of the
most renowned manufacturers and innovative leaders in the
eld of capacitive level measurement. CAPTRON produces
all probes according to the single order and customer-specic
requirements whilst ensuring outstanding quality and reliability.

测量原理测量原理
我公司的电容式液位传感器的测量原理是基于容器内电容的变
化,在这种情况下,液位传感器探测棒与容器壁形成正负两
极,容器内的液体(或固体)充当电介质。容器内液位的变化引
起电容的变化,一个空的容器内电容较低,而一个装满液体的容
器内电容就较高。
选择标准选择标准
容器材质:
如果是金属材质的容器,选择单探测棒的液位传感器即可。
如果是塑料材质的容器,单探测棒或者双探测棒的液位传感器
可供选择。
液体(或固体)介质:
油性介质只需介电常量高于1.8的液体均可以测量,水性介质如
果介电常量较高(高于80)的话,测量精度则与探测棒绝对
度有关。
温度和压力:
一体式的液位传感器中与探测棒紧密连接在一起的放大器可
0-70°C环境下正常工作,而通过导线外接放大器的分离式液位
感器,其探棒可承受最大工作温度可达230°C,同时容器中
的最大压强不能超过10bar
防护等级与连接器件:
所有的产品均具有高达IP67的防护等级。依据不同的设计,我们
的产品可使用M8连接器、M12连接器或固定连接导线的方式来
传输信号。

Measuring principle
The functional principle of our capacitive level measurement
is based on a changing condensator capacity. In this case,
the probe rod and the tank wall form the two electrodes; the
medium functions as dielectric medium. A level change causes
a change in capacity. An empty tank has a low capacity; a lled
tank has a high one.
Selection criteria
Tank material:
In metal tanks, one-rod probes are used.
In plastic tanks either the double-rod probe or
the one-rod probe is used.
Media:
Oily media with a DK value* higher than 1.8 can be detected
without any problems. In the case of watery media with a high
DK value (>80), measurement accuracy is related to the
absolute rod length.
Temperature and pressure:
The temperature range of the medium of the compact probe
(CAPselect) is 0...+70 °C. The probe can be used with a
maximum temperature of 230 °C if provided with an external
amplier. However, the maximum tank pressure of 10 bar must
not be exceeded.
Protection class and device connection:
The different versions are available with a protection class up to
IP67. Depending on the design, the device is connected using
a M8 connector, a M12 connector or a xed cable.
