Measuring this speed allows to optimize the engine speed rate: underspeed measure, overload detection or overspeed (race detection or transmission break, for example), reduction of the noise level, overheating, etc... On of the first speed rotary sensor in the industrial field was the tachogenerator - an electric motor used like a generator. The delivered analogue signal is proportional to the rotation speed. These devices have some disadvantages : the necessity to do regular maintenance of the brush - collector combination, the spark risk which is coming from this combination bans the use of tacho generator in explosive atmosphere and finally, the delivered voltage is wavy, this limits the precision of the system BEI IDEACOD proposes solutions without any contacts based on the incremental encoder technology. The analogue signal is get with the transformation of the signal frequency into proportional voltage or current. The pulses which comes from the optical reading insures a total immunity to perturbations and allows a use on the hardest applications. Moreover the opto-electronic reading principle insures an exceptional life time without any maintenance | | | | | | | | | | OPTO-TACHO | | Shaft | | Speed | | Connection | | | | | | Electronic | | | | | | | | | | | | | | | | | | | Output: V1 : 0...20 mA V2 : 4...20 mA V3 : -20mA ...+20mA Vm : 0...10Vdc Vp : -10V...+10Vdc | | | | | | V6R: radial 12 pins CW M23 connector V3R020: radial 2m PUR cable VBR : terminal box, radial cable gland output | | | | | | 11 : 11mm 12 : 12mm 14 : 14mm 30 : 30mm | | | Example : D10: 10 rpm C20 : 200 rpm M30 : 3000 rpm | | | | | | Power supply: 2 :5Vdc 3 : 15 to 30Vdc | | | | | | | | | | | | | | | | | | | | | | | | | | Solid : 11 12 | | V6R V3R020 VBR | | | | | | 90mm NHM9 90mm NHU9 200mm NHML | | | | | | 3V1, 3V2, 3V3, 3Vm, 3Vp 2V1, 2V2, 2V3, 2Vm, 2Vp | | M60 max. | | | | | | | | | | | | | | | | | | Through : 30 | | 3V1, 3V2, 3V3, 3Vm, 3Vp 2V1, 2V2, 2V3, 2Vm, 2Vp | | M36 max. | | V6R V3R020 | | | | | | | | | | | | | | | Solid : 14 | | 3V1, 3V2, 3V3, 3Vm, 3Vp 2V1, 2V2, 2V3, 2Vm, 2Vp | | M36 max. | | V3R V6R | | | | | | | | | | | | | | | | | | | Reference example | | | | | | 11 // | | // | | | | | | NHM9_ | | | 3V2 | | M36 | | | VBR | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Shaft | Electronic | Out | Pulses | Speed | Connection | | | | | | Na: 0...10Vdc + RS422 | | | | | | | | | | Nc: 0...10Vdc + push-pull | | | | | | | | | | Nd: 0...20mA + RS422 | 9 : | | | | | | | 11 : 11mm | Supply: | Nf : 0...20mA + push-pull | A, A/ B, B/ 0, 0/ | | Example : | N6R: radial 12 pins CW M23 connector N3R020: radial 2m PUR cable NBR : terminal box, radial cable gland output | | | | 12 : 12mm | 2 : 5Vdc 3 : 15-30Vdc | Ng: 4...20mA + RS422 | Number | D10: 10 rpm | | | | 14 : 14mm | Ni: 4...20mA + push-pull | of pulses per turn | C20 : 200 rpm | | | | 30 : 30mm | Nj: -10Vdc... +10Vdc+ RS422 | 0 gated A&B | M30 : 3000 rpm | | | | | Nl: -10Vdc... +10Vdc+ push-pull | | | | | | | | Nm: - 20mA...+20mA + RS422 | | | | | | | | | No: - 20mA...+20mA + push-pull | | | | | | | | Solid : 11 12 | 2Na, 2Nd, 2Ng, 2Nm 3Nc, 3Nf , 3Ni, 2Nj, 3Nl, 3No | 9 | 10000 max | M60 max. | N6R N3R020 NBR | | | | Through : | | 2Na, 2Nd, 2Ng, 2Nm | 9 | 10000 | M36 | N6R | | | | 30 | 3Nc, 3Nf , 3Ni, 2Nj, 3Nl, 3No | max | max. | N3R020 | | | | Solid : | | 2Na, 2Nd, 2Ng, 2Nm | 9 | 10000 | M36 | N3R | | | | 14 | 3Nc, 3Nf , 3Ni, 2Nj, 3Nl, 3No | max. | max. | N6R | | | | 11 // | 3Ni | 9 // | 1024 | M36 // | NBR | | | | | | | | | | | | | | | | | | TACHO-ENCODER | | | | | | | | | | 90mm NHM9 90mm NHU9 | | | | | | È*' | | | | | | | | | | | | | | 200mm NHML NHM9_ | | | | | | Reference example | | | | | | | | | | | | | | | | | | ' IDEACOD | | | | | | | | | www.bei-ideacod.com | | | | | | 35 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
