  1. PID Temperature Controllers

  2. INTRODUCTION Temperature Indicators / Controllers play an important part in any process industry. Quick and accurate measurement / control of a process temperature will improve the final product quality, reliability and reduce rejection. Temperature indication and control is therefore one of the prime considerations in any process industry. The Sleek 92 series is microcontroller based programmable temperature indicator/controller designed for fast and accurate measurement / control. The instrument is designed using highly reliable electronic components. The process temperature is displayed in digits, which gives better resolution compared to analog indicator. The ESD 921 single set point series accepts all types of Pt - 100, Thermocouples, 0 - 20 mA as well as 4 - 20 mA as input.

  3. The instrument is immune to mechanical vibrations. Even the mounting position will not affect the measurement accuracy. The large bright red LED seven segment display allows long distance readability. Use of highly reliable electronic components with lowest temperature coefficient ensure long and trouble free service. The instrument is tested for its performance under various climatic conditions. Wide ranges of measurements are available depending on the sensor used. APPLICATION The Sleek 92 series temperature controllers can be used in almost any industry, laboratory etc. where accurate temperature control is needed to be carried out.

  4. FEATURES Proven troublefree field performance Highly compact Dust and vermin proof enclosure with epoxy powder coating LED display gives better readability at long range Fast response time Highly accurate Available in different DIN std. cutouts Designed for Pt-100, Thermocouples and 4 - 20 mA input Fail safe relay logic Maximum MTBF and minimum MTTR Feather touch push button Wide supply variation and environmental band Minimum overshoot undershoot User friendly programming                
