Our ca­pac­i­tive sen­sors for ob­ject de­tec­tion fea­ture a straight-line elec­tri­cal field. Using this, they rec­og­nize even media with a low di­elec­tric con­stant at a large dis­tance.

Bal­luff sen­sors de­tect liq­uids as well as solid bod­ies such as wafers, printed cir­cuit boards, card­board pack­ag­ing, stacks of paper, bot­tles, plas­tic blocks and boards.

The fea­tures

• Com­pact de­signs from Ø 6.5 mm
• Flat de­signs or disc shapes with a sens­ing dis­tance of up to 25 mm
• Flush in­stal­la­tion
• Plas­tic and stain­less steel de­signs
• Eco­nom­i­cal de­signs avail­able
• Ad­justable via po­ten­tiome­ter or cable teach-in
• Plug and cable vari­a­tions
• Op­tion­ally with IO-Link

BCS ca­pac­i­tive sen­sors are ideal for re­li­able ob­ject and fill level de­tec­tion. This is es­pe­cially true if there are strin­gent tech­ni­cal re­quire­ments and ease of use is vital. The SKF ca­pac­i­tive sen­sor can be glued on quickly, sim­ply, and cost ef­fec­tively. This flex­i­ble sen­sor fully adapts to con­tain­ers and pipes.

The fea­tures

• Flex­i­ble, quickly at­tached and cost-ef­fec­tive
• Con­ve­nient ad­just­ment and eval­u­a­tion via a sep­a­rate ca­pac­i­tive sen­sor am­pli­fier
• Ana­log out­put pos­si­ble
• IO-Link avail­able

Ana­logue ca­pac­i­tive sen­sors de­tect ob­jects with­out con­tact. This means that the ob­jects are not sub­jected to me­chan­i­cal wear. The mea­sure­ment re­sults are there­fore not neg­a­tively af­fected by ob­ject colours or tex­tures. In the case of dif­fer­ent ob­ject ma­te­ri­als, the out­put sig­nal varies from the nor­mal out­put sig­nal of 4 to 20 mA and can be re­turned to the nor­mal out­put sig­nal by means of a user cal­i­bra­tion that is easy to carry out.

The fea­tures

• M18
• Stain­less steel hous­ing
• Flush in­stal­la­tion
• Cur­rent in­ter­face 4…20 mA

Our pas­sive sen­sor heads are used wher­ever a sen­sor with in­te­grated elec­tron­ics would not func­tion op­ti­mally be­cause of the en­vi­ron­ment. For ex­am­ple at ex­treme tem­per­a­tures or under the high­est pres­sures.

Bal­luff’s pres­sure-rated and high-tem­per­a­ture ca­pac­i­tive sen­sors are op­er­ated with a spe­cial triax sen­sor lead and a sep­a­rate am­pli­fier. Their hous­ings are man­u­fac­tured from stain­less steel and their sen­sor heads from PTFE. Thus the sen­sors can be used for de­ter­min­ing the level of flu­ids, pastes or pow­dery media in high-tem­per­a­ture areas to 250 °C as well as at pres­sures to 150 bar.

The fea­tures

• High-tem­per­a­ture-re­sis­tant up to 250 °C
• Pres­sure rated to 6 bar at 180 °C
• Pres­sure rated to 150 bar at 180 °C
• Con­ve­nient ad­just­ment and feed­back via a sep­a­rate ca­pac­i­tive sen­sor am­pli­fier
• IO-Link avail­able

Ca­pac­i­tive mini-sen­sors are the right choice for mea­sure­ment in dif­fi­cult en­vi­ron­ments where dust, re­flec­tions or the prop­er­ties and color of an ob­ject can in­flu­ence the re­sult.

They mon­i­tor stack heights and de­tect solids and liq­uids with ex­treme pre­ci­sion. And through glass or plas­tic con­tainer walls up to 4 mm thick or in di­rect con­tact.

Fine ad­just­ment of the ca­pac­i­tive mini-sen­sors is eas­ily per­formed by means of a sep­a­rate sen­sor am­pli­fier.

This is be­cause their Teflon® sens­ing sur­face makes them par­tic­u­larly re­sis­tant. Their ro­bust stain­less steel hous­ing makes use under dif­fi­cult con­di­tions pos­si­ble as well.

Due to the flat disk de­sign, they re­quire par­tic­u­larly lit­tle space and offer a large switch­ing dis­tance.

The fea­tures

• Ex­tended switch­ing dis­tance
• For dif­fi­cult con­di­tions: Rugged stain­less steel hous­ing
• Very ro­bust thanks to ac­tive sur­face made of Teflon®
• Suit­able for all ma­te­ri­als
• Sim­ple re­mote ad­just­ment via sep­a­rate ca­pac­i­tive sen­sor am­pli­fier
• Pre­cise mea­sure­ment through con­tainer walls up to 4 mm thick or in di­rect con­tact

Ca­pac­i­tive Global sen­sors from Bal­luff for ob­ject and fill level de­tec­tion are just as pre­cise as they are ef­fi­cient. The prod­uct line has al­ready been proven nu­mer­ous times and a large se­lec­tion is avail­able.

The high-qual­ity tech­nol­ogy with op­ti­mum EMC pro­tec­tion has an ex­cel­lent price-per­for­mance ratio and a high level of in­sen­si­tiv­ity to elec­tro­mag­netic in­ter­fer­ence.

The fea­tures

• The se­ries in­cor­po­rates M12, M18, M30 and cuboid vari­ants in cable ver­sion or with M12 con­nec­tor
• Flush ranges up to 20 mm
• Non-flush ranges up to 25 mm
• PNP and NPN ver­sions with nor­mally open or nor­mally closed
• Power-on in­di­ca­tor
• Out­put func­tion in­di­ca­tor
• Avail­able with a plas­tic or stain­less steel hous­ing

Self-ad­he­sive ca­pac­i­tive sen­sor heads de­tect fill lev­els on con­tainer and outer tube walls with­out con­tact.

Their par­tic­u­lar ad­van­tage is their fast, easy and cost-ef­fec­tive mount­ing. They flex­i­bly adapt them­selves to the shape.

It is pos­si­ble to con­tin­u­ously de­tect fill lev­els both anal­o­gously or via IO-Link through the sep­a­rately avail­able am­pli­fiers. As a re­sult, this en­ables the sen­sor to mea­sure the fill level over the en­tire range.

Fea­tures

• Con­tin­u­ously mea­sure with­out con­tact
• Flex­i­ble, quickly at­tached and cost-ef­fec­tive
• Con­ve­nient ad­just­ment and eval­u­a­tion via a sep­a­rate ca­pac­i­tive sen­sor am­pli­fier
• Di­verse ap­pli­ca­tion pos­si­bil­i­ties via the con­ve­nience of ana­log or an IO-Link am­pli­fier
