As a leader in Opacity Meters, beginning with our test cell units, Telonic Berkeley has many years of experience associated with Diesel Smoke Testing and Applications. Currently, we offer two models, the Model TBM300 Portable Opacity Meter, designed to meet and exceed the requirements of the SAE J1667 snap-acceleration test, and the Model 107 Opacity Meter, used primarily for in-line cell testing. Both models operate on the light extinction principal utilizing green LED with a spectral peak between 550 and 570 nanometers. Model TBM300 The Model TBM300 Portable Opacity Meter consists of two basic units connected by a single cable. The sensor unit is installed end-of-line on the exhaust outlet of the vehicle under test and contains the light source (green led) and receiver (photo detector) modules. The sensor head is a cast aluminum (black anodized) housing to provide a stable housing for the Model TBM300 optics. The control unit is battery powered with an alpha numeric membrane keyboard, large LCD display, internal printer and RS-232 data output. The control unit implements software programs to provide many functions required to perform diesel smoke tests. Because more and more local agencies require varying acceptance levels of smoke, the Model TBM300 provides keyboard modification of pass/fail limits. Model TBM300 Features SAEJ1667 compliant Manual mode for continuous testing End of line measurement Range: 0-100% Opacity, 0-30m-1 Smoke Density Accuracy: +-1% Accommodates up to 6 1/2" stack AC and battery powered RS232 output Internal Printer Dual Recorder output 0-100% Opacity, 0-10VDC 0-20% Opacity, 0-10VDC Available Options Tachometer Barometric Pressure Oil Temperature Probe Exhaust Gas Temperature Sensor Control Unit Complete Model TBM300 system in Optional Carrying Cases Click on photos for larger image Model 107 The Model 107 in-line steady state opacity meter is used in diesel engine Test Cell applications by most diesel engine manufacturers worldwide. The control panel is a rack mount chassis with front panel controls. The sensor unit is installed in-line with the optical sensors protected from excessive heat and maintained in alignment by a rugged thermally insulated mount. Assures measurement accuracy because smoke is confined to fixed volume. Optical path length is also fixed, further insuring accuracy and repeatability. Model 107 Features In-line, Full flow Less Drift Rapid Transient Response Greater Precision + or - 0.5% Accuracy Improved Linearity Applicable Specifications ISO/DIS 11614 Euro III EPA 40 CFR 86.884-9 Meets requirements for diesel engine Federal test cycle Measures opacity from 0-100% & Smoke Density from 0-30m-1 Permanent solid-state light source Accomodates 2-12 3/4" diameter stacks. Rack-mounted, all solid-state control unit Not affected by exhaust temperature or vibration Click on photo for larger image 2825 Laguna Canyon Rd., Laguna Beach, CA 92651 TEL:949-494-9401, 1-800-854-2436 FAX:949-497-7331 E-Mail:info@telonicberkeley.com
