round up CONTROL SYSTEMS + AUTOMATION

Double troubleshooting power in test and measurement

fine) plus auto step and auto ramp. • Externally accessible battery for easy battery changes. The 789 has the additional features of 24 V loop power supply and HART mode setting with loop power (adds 250 ohm resistor). Fluke Connect ® compatibility for wire- less data logging (with IR3000FC module)

• Wireless one-step measurement transfer moves away from clipboards, notebooks and multiple spreadsheets. • Measurement data can be shared with the team using ShareLiveTM video calls and emails. Enquiries: Comtest.Tel. +27 (0) 10 595 1821 or email sales@comtest.co.za

The Fluke 787B and 789 ProcessMeters™ from Comtest offer double troubleshooting capabilities by combining the power of a safety-rated, digital multimeter and a mA loop calibrator into a single, compact test tool. Based on the trusted measurement ca- pabilities of the Fluke 87 DMM, the 787B and 789 add the ability to measure, source and simulate mA with the accuracy and resolution that can be expected from a Fluke mA loop calibrator, giving users an ideal tool for troubleshooting and calibrat- ing current loop applications. The 787B and 789 key features: • 20 mA dc current source/measure/ simulate. • Simultaneous mA and % of scale read- out. • DMM designed to meet 1000 volt IEC 61010 CAT III and 600 V CAT IV stand- ards. • Precision 1000 V, 440 mA true-rms dig- ital multimeter. • Frequency measurement to 20 kHz. • Min/Max/Average/Hold/Relative modes. • Diode test and continuity beeper. • Manual step (100 %, 25 %, coarse,

saves time and improves the reliability of maintenance data by wirelessly syncing meas- urements using the Fluke Con- nect ® system. This provides for preventive maintenance to be simplified and ‘reworks’ can be reduced or eliminated. With Fluke Connect ® : • Data-entry errors are elim- inated by saving measure- ments directly from the tool and associating them with the work order, re- port or asset record. • Maintenance decisions are made with trustwor- thy and traceable data. • Baseline, historical and current measurements can be accessed by asset.

Instrotech – Scancon mini rotary encoder

Potential applications range across automated machinery, to pitch and yaw control, small ac motor feedback, wind turbines, pack- aging machines, robotics, remotely operated vehicles (ROVs) and automated guided vehicles (AGVs), solar trackers and automated doors.

The smallest absolute multi-turn encoder Many modern industrial applications demand innovative designs featuring high performance, precise information and smaller com- ponent footprints. Instrotech is offering what is described as the world’s smallest absolute multi-turn encoder with SSI interface, the new mini encoder from Scancon. Based on advanced elec- tronics and mechanics, this high quality, technically sophisticated encoder was developed by Scancon’s engineering team. It opens up new automation possibilities. Scancon designed the encoder to provide a compact, high per- formance solution for motion control applications where space is critical. It features a 24 mm diameter and multi-turn SSI capability. No other encoder on the market offers this solution. Key features of the encoder model 2RMHF – SSI absolute mul- ti-turn include: • Ø24mm footprint • SSI interface • Multi- or single-turn • Hollow blind end or shaft Ø3 mm to Ø6.35 mm • Preset of ZERO position

Scancon’s new mini encoder, designed to suit a host of automation applications.

• Choice of counting direction • Enclosure rating IP64 to IP67 • Cable or Connector version
