Sensaphone FGD-0052 4-20mA Humidity Sensor

Overview

The Sensaphone FGD-0052 4–20 mA Humidity Sensor is a compact environmental sensor designed to provide accurate, real-time humidity readings to any Sensaphone device that accepts a 4–20 mA input. It is ideal for facilities that need continuous humidity monitoring as part of their environmental control strategy, including server rooms, equipment spaces, storage areas, and climate-sensitive environments. This 4–20 mA relative humidity sensor helps integrate humidity into broader facility monitoring and alarm systems.

When connected to a compatible Sensaphone unit, the FGD-0052 allows you to program high and low humidity limits directly in the monitoring system. If the relative humidity moves outside the configured range, the Sensaphone will trigger an alarm and display or report the current humidity value. This makes it easy for technicians and facility managers to maintain safe operating conditions and respond quickly when humidity levels become unacceptable.

The sensor is designed for installation flexibility, with a low-profile enclosure that can be mounted directly on a wall or in a single-gang electrical box. It measures humidity from 0 to 95% RH and requires a 24 V DC external power supply. By leveraging a standard 4–20 mA output signal, the FGD-0052 integrates cleanly into existing measurement equipment and environmental monitoring systems that rely on industrial control signals.

Key Features

• 4–20 mA output provides a standard industrial signal for humidity monitoring.

Applications

This sensor is well suited for technicians, facility managers, and environmental monitoring professionals who need reliable humidity measurement integrated into Sensaphone monitoring equipment. It supports long-tail environmental monitoring applications across commercial, industrial, and critical infrastructure environments.

• Server rooms and telecommunications spaces requiring humidity supervision.
• Mechanical and equipment rooms where condensation or dryness may cause damage.
• Storage areas and warehouses with humidity-sensitive inventory.
• Laboratories and controlled environments needing continuous humidity tracking.
• General facility monitoring where humidity is part of broader environmental control.

Performance and Characteristics

The FGD-0052 provides a proportional 4–20 mA output that maps directly to the 0–95% RH measurement range, allowing Sensaphone units to interpret humidity with consistent accuracy. Compared to simple on/off humidity switches, this analog output delivers more detailed feedback and tighter control over alarm thresholds. When paired with a Sensaphone monitoring system, it enables programmable high and low humidity limits that trigger alarms as soon as conditions drift out of specification, improving response time and reducing the risk of environmental damage.

Additional Information

The low-profile housing is designed for clean, unobtrusive mounting in occupied or equipment spaces. Because it uses a 4–20 mA signal, the sensor can operate over longer cable runs than many voltage-output devices, supporting flexible placement in larger facilities. A dedicated 24 V DC power supply is required to operate the sensor.
