Sigma Automation is focused towards design, manufacture and supply of quality products for process control and measurement of parameters like temperature, pressure, humidity, flow, voltage, current etc. Established in 1995,is poised to be leaders in this area.

Sigma Automation Pvt Ltd provides products are:
The product range includes Data logger, scanners, data acquisition systems, temperature and process controllers, transducers, transmitters, convectors, solid-state relays, sensors, timers and counters. The Products section of this site provides more details of these.

Their Products Range:
1. Series TI Digital Indicators and Scanners:
Series TI Digital Indicators are panel mount process indicators to display parameters like temperature, pressure, humidity, voltage, current, etc. Single point and multipoint indicators are available in this series. Optionally, the measured value can be provided as an analog output or RS 232 / RS 485 serial output
2. Data Loggers:
Data loggers are stand-alone equipment, which accept analog inputs, display and log the measured value along with date and time either to a PC or to a printer.
3. Controllers:
Controllers accept analog inputs, display the measured value and control the output (relay, ssr, thyristor, etc.). On-off or proportional control modes available.
4. Transmitters:
Transmitters accept analog inputs and convert the analog value into a proportional voltage or current depending on the requirement. The common analog inputs are temperature, pressure, humidity, flow, voltage, etc.. Common outputs are 4-20 mA, 0-20 mA, 0-10V, 0-5V and 0-1V. Isolated and non-isolated models are available.
5. Digital Timers:
Digital timers are basically time relay switches, where the time is set and a relay is activated after the elapsed time. The set time and the elapsed time are displayed on the front display. Universal timers are available, where the user can configure the set time,unit of time, relay logic and mode of operation.
6. Digital Counters:
Digital counters accept count inputs from sensors like proximity switches, optical switches and display the counts on a display.

Their Services: Sigma Automation provides total solutions in industrial automation and process control through system integration. They provide services in Programmable logic controller (PLC) integration, Microprocessor and Embedded software development and application software development.
