Signal conditioning
International approval for highly compact signal conditioners
series from Phoenix Contact now have ATEX and IECEx approval for zone 2, which represents an extensive update in the international approval program for explosion protection. The products can now be installed in zone 2 potentially explosive areas worldwide in a housing with the IP54 degree of protection. The advantages of the highly

compact signal conditioners and measuring transducers with pluggable connection technology remain. In an overall width of only 6.2 mm, the modules provide terminal points that are easy to view and reach, allowing significant time

savings during installation. In addition, current signals can be measured without interrupting downstream processes. Alongside the classic DIP
switch parameterisation, a free app and software solutions are available. The app has a special feature: with the help of embedded NFC chips, the modules can be written without an additional power supply. Process values are directly
integrated into digital communication protocols such as PROFINET via optional snap-on gateways that feature a simple ‘Plug and Play’ concept and extensive combination options for signal types.

ewTek Sensor Solutions have introduced a new series of Difference/ Sum LVDT Signal Conditioners that
improve a sensor’s performance during large temperature variation. By measuring the difference of the output over the sum (S1- S2)/(S1+S2), the NTC-6000-DS Quick-Cal LVDT Signal Conditioner compensates for changes in resistance in copper windings due to temperature fluctuations. As a result, the Ratiometric Signal Conditioner is ideal for use with AC- LVDTs in harsh environments with extreme temperature swings such as aerospace test stands, packaging equipment, factory automation, turbine control systems and steam valve positioning. Users of the NTC-6000-DS LVDT Signal Conditioner can select between a ratiometric Diff/Sum measurement or differential (standard) measurement. Based on the proven and reliable platform of the NTC-6000 LVDT Signal Conditioner, this standalone unit offers: selectable ratiometric Diff/Sum measurement or differential (standard) measurement; compatibility with almost any AC-LVDT; self- diagnostics for sensor failures, disconnects or short circuits; cybersecurity lock out and tamper detect; voltage, current and digital; digital protocols include Modbus, CAN Bus, RS-485 and more; hot swap reconfiguration where setup is saved and reloaded via the RS- 485 port; intuitive setup for quick

configuration by non-technical personnel; and selectable excitation frequency, analogue outputs and bandwidth The NTC-6000-DS LVDT Signal
Conditioner is compatible with standard and constant sum AC LVDTS and RVDTs including NewTek’s NT-HT-1000 High Temperature LVDT Position Sensor Series designed for difference/sum measurement. These smart signal conditioners are RoHS compliant and CE-certified for use in Europe.
NewTek offers the NTC-6000 Signal Conditioner with a two-year warranty. The company accepts small- to large-sized orders and guarantees on-time delivery of units. NewTek can accommodate customisation requests to conform to a specific package, non-standard analogue or digital outputs, and heightened environmental ratings.
