Highlights

  • Ultrasonic transducer protected by PEEK film for simple cleaning and high resistance to wear
  • Stainless-steel housing
  • Digital display with direct measured value output in mm/cm or %
  • IO-Link interface for support of the new industry standard
  • Numeric configuration of the sensor using digital display permits the complete advance configuration of the sensor
  • Automatic synchronisation and multiplex operation for simultaneous operation of up to ten sensors in close quarters

Basics

  • 1 Push-Pull switching output pnp or npn basis
  • 1 or 2 switching outputs in pnp variant
  • Analogue output 4–20 mA and 0–10 V with automatic switching between current and voltage outputs
  • 5 detection ranges with a measurement range of 30 mm to 8 m
  • microsonic Teach-in using T1 or T2 buttons
  • 0.025 mm to 2.4 mm resolution
  • Temperature compensation
  • 9–30 V operating voltage
  • LinkControl for configuration of sensors from a PC

Description

Sensor membrane with wear-resistant protective film

In many filling processes, spray on the sensor membrane simply cannot be avoided. These sprays often harden so that after longer periods of operation contamination can only be removed from the sensor membrane by mechanical means. The new protective film of the crm+ sensors now makes it easy to remove caked-on soiling, such as hardened casting compound and cement spatter.

The protective film is also highly resistant to corrosive media. The threaded sleeve is made of 1.4571 stainless steel.

TouchControl with LED display - Wear-resistant PEEK protective film

There are three output stages available for all five detection ranges:

1 pnp switching output, optionally in pnp or Push-Pull circuitry
2 pnp switching outputs
1 analogue output 4–20 mA and 0–10 V

The crm+ sensors with switching output have three operating modes:

  • Single switching point
  • Two-way reflective barrier
  • Window mode

With TouchControl

all configuration can be done right at the sensor. The easily legible three-digit LED display continually shows the current distance value and automatically switches between millimetre and centimetre displays.

Setting a switching or analogue output

can optionally be carried out by numeric input of the desired distance values, or using a teach-in procedure. This permits the user to select the configuration method preferred.
The crm+ sensors support synchronisation and multiplex operation and have extensive parameterisation options via LinkControl. For detailed information, please see at mic+ sensors .

LinkControl 

consists of the LinkControl adapter and the LinkControl software and facilitates the configuration of the crm+ sensors via a PC or laptop with any conventional Windows® operating system.

Sensor connected to the PC via LCA-2 for programming

IO-Link integrated

in version 1.1. The crm+ ultrasonic sensors are equipped with Smart Sensor Profile, which creates more transparency between IO-Link devices.
