Ultrasonic sensor for precise measurement in harsh industrial environments

With the 2U Indus­try ultra­son­ic sen­sor, the elobau com­pa­ny offers a reli­able and con­ve­nient way to mea­sure fill lev­els and detect objects. Elobau is a glob­al­ly active man­u­fac­tur­er of non-con­tact sen­sor tech­nol­o­gy, lev­el mea­sure­ment and oper­at­ing ele­ments for mechan­i­cal and plant engi­neer­ing as well as mobile machin­ery based in Leutkirch.
Thanks to the high vari­abil­i­ty and flex­i­bil­i­ty of the prod­uct, the sen­sor is suit­able for almost any type of lev­el appli­ca­tion. Regard­less of the trans­paren­cy, gloss, sur­face con­di­tion and col­or of the liq­uid or mate­r­i­al, the 2U Indus­try deliv­ers pre­cise results, even in harsh indus­tri­al environments.
Com­mis­sion­ing is quick and easy. The ultra­son­ic sen­sor mea­sures with­out con­tact, which means that no mov­ing or mechan­i­cal parts are used in the mea­sure­ment. As a result, the oper­a­tor ben­e­fits from min­i­mal main­te­nance requirements.

Focus on flexible use and ease of operation

With regard to the out­put sig­nals, the user can choose between an ana­log cur­rent or volt­age sig­nal. In addi­tion, up to four freely pro­gram­ma­ble switch­ing out­puts (high-side / low-side) are avail­able. The ultra­son­ic sen­sor was prefer­ably devel­oped for lev­el mea­sure­ment of liq­uid media and solids such as gran­u­lates, but can also be used for dis­tance mea­sure­ment to objects, walls or soil. The user has the pos­si­bil­i­ty to car­ry out con­tin­u­ous lev­el and point lev­el measurements.
The para­me­ter­i­za­tion of the sen­sor is menu-dri­ven with the help of the dis­play and a key (teach-in key). The easy-to-read dis­play shows the lev­el. The rotat­able head of the sen­sor allows an opti­mum view of the dis­play at all times as well as addi­tion­al flex­i­bil­i­ty for mount­ing in dif­fi­cult instal­la­tion sit­u­a­tions. Regard­ing the mount­ing threads, vari­ants with G 1.5″, G 2″, 1.5″ NPT and 2″ NPT are avail­able. The 2U Indus­try is suit­able for appli­ca­tions where the range of the sen­sor can be up to 1 m and the ambi­ent tem­per­a­ture ranges between ‑20°C and +70°C.

Added value thanks to ultrasound

The prin­ci­ple of ultra­son­ic tech­nol­o­gy is as sim­ple as it is effec­tive. Ultra­son­ic sen­sors cycli­cal­ly trans­mit sound puls­es in the high-fre­quen­cy ultra­son­ic range in the direc­tion of their tar­get object. The tar­get reflects the sig­nal, which is received by the sen­sor as an echo. The dis­tance can then be cal­cu­lat­ed from the tran­sit time.
This mea­sur­ing prin­ci­ple allows not only dis­tances to be mea­sured, but also the posi­tions of objects to be detect­ed — even in pre­cip­i­ta­tion, humid­i­ty, dust, smoke and extreme tem­per­a­tures. This makes the ultra­son­ic sen­sor an all-round tal­ent that is suit­able for a wide vari­ety of mea­sure­ment and mon­i­tor­ing tasks.
