Its fast response time and high long-term stability ensure reliable measurements, making it suitable for both industrial and commercial duct systems.

Versatile Output and Easy Installation

The KLK transmitter supports selectable analog outputs (4-20mA or 0-10V) and offers both 2-wire and 3-wire connectivity. Screw terminals and a PG9 cable gland simplify installation. The lightweight, compact design fits standard duct mounts, streamlining integration into new or existing setups.

Durable and Standards-Compliant Construction

Enclosed in a robust ABS plastic housing with IP65 protection, the KLK transmitter withstands challenging environments. Compliant with CE marking standards, it provides peace of mind regarding safety and compatibility in professional applications throughout India.

FAQ's of Duct Humidity Transmitter KLK:

Q: How is the KLK Duct Humidity Transmitter installed in an air or gas duct?

A: The transmitter is designed for direct duct mounting using the integrated 19 mm probe. It features screw terminals for straightforward electrical connection and a PG9 gland for secure cable entry, simplifying the installation process within HVAC or industrial duct systems.

Q: What benefits does the fast response time (<10 seconds) provide?

A: A rapid response time ensures near-instantaneous humidity monitoring, allowing for immediate detection of environmental changes. This is particularly advantageous in dynamic air and gas applications where system control depends on timely, accurate readings.

Q: When should the output signal be set to 4-20mA or 0-10V?

A: Choose 4-20mA output for longer cable runs and when minimal signal loss is critical; select 0-10V for shorter distances or when integrating with controllers that accept voltage signals. Both output signals are selectable based on your system's compatibility requirements.

Q: Where can the KLK Duct Humidity Transmitter be used?

A: Primarily used in HVAC ducts and air handling units, the transmitter is ideal for applications requiring precise air or gas humidity measurement. Its IP65 protection and CE compliance make it suitable for commercial, industrial, and institutional environments across India.

Q: What maintenance is required to ensure long-term accuracy?

A: The device requires minimal maintenance due to its capacitive sensor and robust design. Routine inspection of probe and periodic cleaning in dusty or contaminated environments will help maintain high long-term stability (1% RH/year) and consistent accuracy.

Q: How does the LCD display enhance device usage?

A: The built-in LCD provides real-time humidity readings and device status, supporting quick diagnostics, calibration, and on-site configuration without needing additional tools or instruments.
