Limit value switches

ACS-CONTROL-SYSTEM

Fill level measurement technology from ACS-CONTROL-SYSTEM offers sensors for continuous measurement and point level detection in liquids and bulk solids. Due to the comprehensive selection of measuring principles and device types, we can offer a solution for every task. Fill levels or level measurement can be done with displacement sensors. For precise level control measurement, confocal sensors or laser triangulation sensors are typically used. For long ranges, such as silo fill level, laser rangefinders are used to measure material levels at a longer distance.

Our quote will always be lower than the manufacturer's price. Please send us the full part number of a device to get a quick response.

Capacitive level switch Capcont M

Capacitive level switch
Capcont M

Made in Germany

Description

The level limit switch Capcont M with integrated evaluation electronic are compact fill level limit switches for supervision of fill levels in liquids and solid materials in containers or pipelins at process temperatures from -30°C to +125°C and process pressures from -1 up to 10 bar.

The sensor is suitable for limit value detection or also as dry run protection in liquids and viscous substances but also in powdery and fine-grained materials, like e.g. grain, flour, powdered milk, mixing food, cement, chalk or gypsum. It can be used in electrically conductive as well as non-conductive materials.

Function

The fill level limit switch Capcont M is a capacitive operating sensor with limit value detection. Electroden rod, filling material and container wall realizes an electrical capacitor. A fill material changing causes a capacity change that is evaluated by the electronic and is converted into a corresponding switching reaction.

At transgression or underrun of the limit value a switching signal at the PNP switching output is created. This allows a control of relays, contractors, magnetic valves, light signaling units, horn as well as SPS inputs. A plugable yellow LED indicates an active PNP switching output. A possibility for change over the minimum / maximum safety is integrated.

Capacitive level switches
Capcont LL
Capcont LS

Made in Germany

Description

The level limit switch Capcont LS is suitable for limit value detection of also as dry run protection in liquids and viscous substances and also in powdery and fine granular substances. Like e.g. grain, flour, powdered milk, mixing food, cement, chalk or gypsum.

It can be used in electrically conductive as well as in non-conductive materials. The device is certificated for the use as overflow protection acc. to WHG.

Capcont LS with integrated evaluation electronic is a compact filling level limit switch for supervision of filling levels.

Function

The device is a capacitive operating sensor for limit value detection. Electrode rod, filling material and container wall creates an electrical capacitor. The contact of the electrode rod with the filling material produces a variation in capacity. That is evaluated by the electronic and converted in a correspondent switching action. The detection of a filling level signal is indicated at the plug side of the device by a yellow LED and converted into a switching command and output at the PNP switching output. This allows the drive of relays, contactors, magnetic vents, optical indicators, horns as well as of SPS inputs.

At a switching reaction, the voltage of the connection terminal 1 (+L) is output alternating by two contrary operated semiconductor switches at two connection terminals. The adjustment of the responsitivity of the device to the respective filling material is done by a potentiometer.

Capcont LS is mounted from the top side of the pressure container or of the pipe. Capcont LL is mounted from the top side or into the side wall of the pressure container or of the pipe.
