Nagano Keiki Kh25 Pressure Transmitter

What is the KH25 Pressure Transmitter?

The KH25 series by Nagano Keiki is a small, high-performance transmitter designed for use in commercial and industrial applications. As a device for converting applied pressure to an electrical signal, it supplies real-time, continuous, and accurate measurement of system pressure.

With a history of innovation spanning decades, Nagano Keiki (a member of the former Nagano Keiki Group) is well-known around the world for its provision of precision instruments utilized in life-critical applications across numerous industries.

Key Characteristics of the KH25 Pressure Transmitter

Broad Pressure Range Choices
The KH25 is also presented in various configurations of pressure ranges, meaning it can cater to low-pressure as well as high-pressure applications. If your system has vacuum conditions or needs to measure up to several hundred bars, the KH25 is easily adaptable.

High Accuracy and Long-Term Stability
Accuracy is paramount for applications in which even minute deviation may result in processing inefficiencies or safety hazards. KH25 provides high accuracy of measurement (normally ±0.5% F.S.) and superior long-term stability, ensuring reliable operation over years of service.

Compact, Robust Construction
Designed for space-limited locations, the compactness of the KH25 facilitates easy installation. Its stainless steel construction offers excellent resistance to mechanical impact, corrosion, and harsh environments.

Multitude of Output Options
The pressure transmitter has various output signal options (e.g., 4–20mA, 0–5V, 0–10V), allowing for easy interface with PLCs, DCS systems, and other industrial controllers.

Harsh Environment IP-Rating
The KH25 has IP-rated protection (usually IP65 or above), which makes it ideal for application in dusty, wet, or high-vibration environments such as chemical plants, refineries, and outdoor facilities.

Applications of Nagano Keiki KH25

The KH25 is a multi-purpose product used in various industries, such as:

1. Hydraulic and Pneumatic Systems
The KH25 maintains adequate pressure levels in hydraulic machines, pneumatic tools, and automation control systems. It is a vital component to ensure the operational efficiency of the system and prevent system failure.

2. Water and Wastewater Treatment
Precise pressure monitoring is important for pump systems, filtration equipment, and pipe networks. KH25 is used to provide stable flow and system pressure in water management facilities.

 3. Oil & Gas Sector
During upstream, midstream, and downstream operations, preserving precise pressure data is essential to ensure safe operations. The KH25 is useful for pressure monitoring and control of tanks, pipelines, and compressors, respectively.

 4. HVAC and Building Automation
Applied in HVAC systems to regulate airflow, heating, and cooling cycles, the KH25 transmitter reduces energy consumption and ensures indoor comfort.

5. Industrial Process Control
In manufacturing plants, particularly in chemical and pharmaceutical industries, pressure measurement is crucial for batch control, safety monitoring, and product quality maintenance.
