Laser Probes. RF609, RF609Rt Series

Laser Probes. RF609, RF609Rt Series Safety precautions · · · · Use supply voltage and interfaces indicated in the probe specifications. In connection/disconnection of cables, the probe power must be switched off. Do not use the probe in locations close to powerful light sources. To obtain stable results, wait about 20 minutes after powering on to achieve uniform probe warm-up. The probes have been developed for use in industry and meet the requirements of the following Directives: · EU directive 2014/30/EU. Electromagnetic compatibility (EMC). · EU directive 2011/65/EU, “RoHS“ category 9. Laser...

Laser Probes. RF609, RF609Rt Series Measuring principle The measuring principle is illustrated in Figure 2. The laser probe is inserted into the controlled hole. The probe or the part is driven in rotation. A triangulation laser sensor, which is built into the probe, measures the distance to the hole surface synchronously with the angle of rotation. The resulting set of polar coordinates is used to calculate the geometric parameters of the hole. Moving the probe along the hole allows you to get the geometric parameters of the hole in different sections and build a 3D model of the inner surface....

Laser Probes. RF609, RF609Rt Series NOTE 2. Increasing this parameter expands the possibility of control of lowreflecting (diffuse component) surfaces; at the same time this leads to reduction of measurement frequency and increases the effects of exterior light (background) on the measurement accuracy. Factory setting of the limiting time of integration is 3200 s. NOTE 3. Decreasing this parameter makes it possible to increase the measurement frequency, but can decrease the measurement accuracy. Sampling mode This parameter specifies one of the two result sampling options in the case where the...

Laser Probes. RF609, RF609Rt Series Method of results averaging This parameter defines one of the two methods of averaging of measurement results implemented directly in the sensor: · Averaging over a number of results · Time averaging When averaging over a number of results is selected, sliding average is calculated. When time averaging is selected, the results obtained are averaged over the time interval chosen. Number of averaged values / time of averaging This parameter specifies the number of source results to be averaged for deriving the output value or time of averaging (discreteness -...

Laser Probes. RF609, RF609Rt Series Serial data transmission format The data message has the following format: 1 start-bit The even parity bit pads 8-bit data to even parity. Modes of data transfer Through these serial interfaces the measurement data can be obtained by two methods: · by single requests (inquiries); · by automatic data streaming (stream). Communication sessions types The communications protocol is formed by communication sessions, which are only initiated by the ‘master’ (PC, controller). There are two kinds of sessions with such structures: 1) “request”, [“message”] — [“answer”],...

Laser Probes. RF609, RF609Rt Series RIFTEK protocol (binary format) 'Request' is a two-byte message, which fully controls a communication session and can be transmitted by the 'master'. The ‘request’ message is the only one of all messages in a session where the most significant bit is set at 0, therefore, it serves to synchronize the beginning of the session. In addition, it contains the device address (ADR), code of request (COD) and, optionally, the message [MSG]. Request format ('master'): lower tetrad of the 0th byte higher tetrad of the 0th byte lower tetrad of the 1st byte higher tetrad...
