🖹 Description
The Fisher 646 electro-pneumatic transducer uses a converter module that converts a 4 to 20 milliampere
input signal to a proportional 0.2 to 1.0 bar (3 to 15 psig) pneumatic output signal. The converter module uses small parts of minimum mass, which are balanced symmetrically around a pivot point at the center of the mass. This balanced arrangement results in a high performance instrument that reduces sensitivity to vibration.
Input Signal:4 to 20 mA DC, constant current with 30 VDC maximum compliance voltage
Output Signal:0.2 to 1.0 bar (3 to 15 psig) direct acting only
Supply Pressure
Recommended: 1.4 bar (20 psig)
Minimum: 1.4 bar (20 psig)
Maximum: 3.4 bar (50 psig)
The IP Transducer FISHER 646 (Type 646) is a reliable and high-precision signal conversion device designed for industrial automation and process control applications. Part of the renowned FISHER (EMERSON) product line, this I/P converter is widely recognized for its performance, durability, and accuracy in demanding environments.
The primary function of an I/P (current-to-pressure) transducer is to convert an electrical input signal—typically a 4–20mA current signal—into a proportional pneumatic pressure output. This output is used to control pneumatic actuators and control valves, making the device essential in process control systems where precise regulation of pressure, flow, temperature, and level is required.
The FISHER 646 I/P Converter delivers high conversion accuracy and stable performance, ensuring reliable signal transmission and consistent process control. This contributes to improved system efficiency, reduced operational errors, and enhanced process stability in industrial applications.
The robust construction of the Type 646 makes it suitable for operation in harsh environments, including conditions with high humidity, vibration, temperature fluctuations, and industrial contaminants. It is commonly used in industries such as oil and gas, petrochemical plants, power generation facilities, and heavy industrial processes.
Designed for long-term reliability, the unit requires minimal maintenance, helping to reduce operational costs and improve system uptime. Its straightforward installation allows for easy integration into existing control systems without the need for extensive modifications.
FISHER, a brand under EMERSON, is a global leader in industrial control instrumentation, known for delivering high-quality and dependable solutions. The Type 646 model meets the demands of modern process control applications, providing accuracy, durability, and consistent performance.
