Temperature Transmitter

Temperature Transmitter

Product Overview

The VSAN Temperature Transmitter is a high-performance field-mounted or head-mounted industrial transmitter designed to accurately convert temperature signals from RTD, PT100, Thermocouple (TC), Resistance (Ω), and Millivolt (mV) sensors into a standardized output signal for process control and automation systems. It provides highly accurate, stable, and reliable temperature measurement while ensuring seamless integration with modern industrial control systems.

In industrial process automation, the raw signal generated by temperature sensors is often weak and susceptible to electrical noise, signal loss, and interference over long transmission distances. The VSAN Temperature Transmitter conditions, amplifies, linearizes, and converts these sensor signals into industry-standard 4–20 mA, HART, RS485 Modbus RTU, or other communication outputs, enabling precise and reliable temperature monitoring even in harsh industrial environments.

The VSAN Temperature Transmitter supports a wide variety of input sensors, including RTD (PT100, PT500, PT1000), Thermocouples (Type K, J, T, E, N, R, S & B), resistance inputs, and millivolt signals, making it suitable for virtually all industrial temperature measurement applications. It features universal input capability, allowing users to configure different sensor types using software or programming tools without changing the hardware.

Manufactured using industrial-grade electronic components and housed in a rugged IP65/IP67-rated aluminium or stainless steel enclosure (model dependent), the transmitter is designed to withstand vibration, moisture, dust, corrosion, and wide ambient temperature variations. It is available in Head Mount, DIN Rail Mount, Field Mount, and Explosion-Proof configurations, providing flexibility for installation in a wide range of process environments.

The transmitter offers high measurement accuracy, excellent long-term stability, fast response time, and advanced diagnostic functions to ensure reliable process monitoring. It is fully compatible with PLC, DCS, SCADA Systems, HMI, Data Loggers, Distributed Control Systems, and Industrial Automation Networks, making it an ideal solution for continuous process temperature measurement.

Designed in compliance with international standards and industrial communication protocols, the VSAN Temperature Transmitter simplifies installation, improves measurement accuracy, reduces wiring costs, and enhances overall process efficiency.

The VSAN Temperature Transmitter is widely used in Oil & Gas, Chemical Processing, Petrochemical Industries, Power Plants, Food & Beverage, Pharmaceutical Manufacturing, Water & Wastewater Treatment, Steel Plants, Cement Industries, HVAC Systems, Marine Applications, Paper & Pulp Mills, OEM Equipment, and Industrial Automation, where accurate and dependable temperature signal transmission is essential.

With its universal sensor compatibility, rugged construction, high accuracy, and advanced communication capabilities, the VSAN Temperature Transmitter provides a reliable and cost-effective solution for industrial temperature measurement and process control.

Working Principle

The VSAN Temperature Transmitter operates on the Signal Conditioning and Analog/Digital Conversion Principle.

The transmitter receives a low-level electrical signal from an RTD, PT100, thermocouple, resistance sensor, or millivolt input. An internal microprocessor accurately measures the input signal, performs linearization, cold junction compensation (for thermocouples), and temperature conversion based on internationally accepted standards.

The processed temperature value is then converted into a standardized 4–20 mA analog output or digital communication signal such as HART or RS485 Modbus RTU, depending on the transmitter model.

The output signal is transmitted over long distances to PLCs, DCS, SCADA systems, or process controllers without significant signal degradation, ensuring accurate and reliable temperature monitoring throughout the plant.

Advanced models also provide self-diagnostics, sensor failure detection, configurable measuring ranges, and programmable output settings for enhanced process reliability.
