ESD 92 series
1. Introduction
Temperature Indicators and Controllers
play an important part in any process
industry. Quick and accurate measurement
and control of 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 ESD 92 series is a On / Off type Digital
Temperature Controller designed for fast
and accurate measurement and control. The
instrument is designed using highly reliable
e l e c t r o n i c c o m p o n e n t s . P r o c e s s
temperature is displayed directly in digits,
giving better resolution compared to analog
indicators.
The ESD 92 series accepts all types of
Thermocouples, Pt - 100, 0 to 20 mA, 4 - 20
mA as well as 0-2/5/10 V DC as input . Wide
ranges of measurements are available.
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
low temperature coefficient ensure long and
trouble free service. The instrument is
tested for its performance under various
climatic conditions.
