Zettlex. Precision in the Extreme

2 Zettlex is a sensors company. We design, make and sell sensors & sensor components for position and speed measurement. Flow metering Our company motto is signifying that even in harsh environments, our sensors remain accurate and reliable. Extreme environments might mean high or low temperatures, tight spaces, high pressures, fluid immersion, chemical attack, vibration, shock, weight limits, low power, electromagnetic noise, aggressive or extended duty cycles. Extreme precision might mean, for example, measuring 16 million steps over one revolution of a rotary encoder or measuring sub-micron displacements of a linear sensor. Plant monitoring Zettlex s unique non-contact technology measures displacement using a patented inductive technique. This enables no contacts, no bearings, no bushes, no seals, no fine wires, no delicate components just reliable measurements all day, every day. The main parts of our sensors are laminar, printed circuits and this means lightweight, compact designs that can be readily shaped to tight or unusual space envelopes. Sensors are available in a wide range of shapes & sizes such as rotary, annular, linear, curvi-linear, 2D and multi-axis. Linear sensors range from 0.1 to 2700mm and rotary units measure continuously over 360 degrees or multiple rotations. Pan & tilt controls Rotary units are also used as high speed motor encoders or wireless torque transducers.

3 As well as a wide range of custom and semi-custom products, we offer 2 standard ranges IncOder rotary units and LINTRAN linear units. IncOder IncOders are precision angle encoders. They are ideally suited to applications that need reliable operation in harsh environments where electrical contacts, optical or capacitive devices may prove unreliable. Low profile and a large through bore makes it easy to accommodate shafts, slip rings, optic fibres, pipes or cables. Radar Applications include rotary joints, gimbals, electro-optic equipment, weapons systems, robotics and automation. IncOders offer a highly economical, accurate and lightweight alternative to pancake resolvers. LINTRAN LINTRAN linear units provide a simple and robust method for linear position measurement over mm. Field programmable without the need for a PC, LINTRANs offer a cost effective alternative to potentiometers or magnetostrictive devices. Weapons Systems Zettlex Linear Actuators

4 Custom & Semi-custom Products We have a library of hundreds of sensor designs which can be readily customized to suit specific requirements. Typically, technical requirements are met by combining elements from existing designs. Sensors can be designed to withstand : Long term immersion Extended life-time Chemical attack Potentially explosive (ATEX) environments Temperatures from -55 to 85, 125 or 230 o C Aggressive vibration including mechanical shock to 1000g Lightning strike, over voltage and reverse polarity. Flight controls Generally, sensor accuracy is unaffected by mounting offsets or tolerances. Pathways for cables or shafts can be provided through the sensors for easy installation. The sensor's environmental operating envelope can be expanded by remote location of electronics. Absolute or incremental outputs are available including 0-5V, 0-10V, 4..20mA, SSI, SPI, PWM, I 2 C, RS232, RS485, MODBUS etc. In some applications, unit costs can be reduced with a single electronics module controlling multiple sensors. Actuator controls In safety applications, electrically redundant sensors can be supplied with on-board monitoring & diagnostics. For aerospace and safety critical applications, sensors can be provided with software approved to D0178B or, alternatively, without software.

5 Absolute rotary position transducer optical encoder position displacement sensor Netzer Inductosyn BEI Sick Hall Magnetic Resolver LVDT Penny GilesHoneywell OUTLINE PRODUCT DATA SHEET Zettlex Rotary Encoders Zettlex Rotary Encoders are non-contacting, absolute, angle and speed measuring devices. They utilise a unique inductive technique and comprise two main components a Target and an Antenna. The Antenna is powered with an electrical supply and can be moving or stationary. An electrical output from the Antenna shows the position of the Target relative to the Antenna. The Target has no electrical connections and can be moving or stationary. No contacts, no bearings, no bushes, no fine wires.. just reliable measurements all day, every day. Zettlex Rotary Encoders offer a cost effective alternative to resolvers, synchros, magnetic or optical encoders. The units do not require precision mounting and can operate reliably without any housings. Even unhoused, the performance of conformally coated units is generally unaffected by fluids, dust, dirt, temperature, shock, vibration or electromagnetic noise. Most units are produced using printed circuit boards from 0,1 to 12mm thick. Control electronics can be provided onboard the Antenna or away from the sensing area in more benign environments. Sensing area temperature limits range from -70 to >200Celsius. All rotary units can be readily engineered to specific customer requirements in terms of accuracy, speed, size, electrical characteristics, temperature range etc. - simply contact Zettlex for further details.
