XM-18 Digital Automatic Small Egg Incubator Thermostat Controller with Temperature and Humidity Sensor Double Circuit

The XM-18 is a precision digital thermostat controller specifically engineered for small-scale egg incubation systems, featuring dual-circuit architecture for independent temperature and humidity regulation. Poultry farmers, hatchery operators, and agricultural research institutions rely on this controller to maintain critical incubation parameters within 0.1 degree Celsius accuracy and humidity tolerance of plus or minus 2 percent RH. This device eliminates manual monitoring and prevents embryo mortality caused by temperature fluctuations and suboptimal humidity levels during the critical 21-day incubation cycle.

Product Overview

The XM-18 operates on a dual-circuit control system where the primary circuit manages heating elements through a PID-based temperature algorithm, while the secondary circuit independently controls humidification systems using relay-based switching. The controller utilizes a calibrated NTC thermistor sensor with 10k ohm resistance at 25 degrees Celsius and a capacitive humidity sensor with 0 to 100 percent RH detection range. This dual-circuit architecture prevents thermal overshooting and humidity lag by allowing simultaneous independent adjustments, critical for maintaining the precise 37.5 degrees Celsius and 40 to 60 percent RH environment required for optimal chicken embryo development.

The XM-18 features a digital LED display showing real-time temperature and humidity values with a 2-line 16-character alphanumeric interface. The control logic is managed by a microcontroller-based system with non-volatile EEPROM memory that retains setpoint parameters even during power loss. The device includes both heating and cooling relay outputs rated at 10 amperes each, allowing integration with heating coils, heat lamps, humidifiers, and ventilation systems. Built-in hysteresis settings prevent relay chatter and extend component lifespan, while the programmable control window allows users to set different temperature and humidity profiles for different incubation stages.

How to Use

Installation begins by mounting the XM-18 controller on a standard 35mm DIN rail within your incubator cabinet or control enclosure, ensuring adequate ventilation around the device. Connect the temperature sensor to the marked terminal block, routing the sensor probe into the incubator chamber at the center height where embryos are positioned. Similarly, connect the humidity sensor probe ensuring it has access to chamber air without direct contact with water sources. Wire the heating element circuit to the heating relay output terminals and the humidification system to the humidity relay output terminals, ensuring all connections are rated for the current draw of your specific heating and humidification equipment. Apply AC power and the display will initialize showing current temperature and humidity readings.

Configure the device by pressing the menu button to access setpoint adjustment screens. Set your desired incubation temperature, typically 37.5 degrees Celsius for chicken eggs, and humidity level appropriate for your embryo type and incubation stage. For the first 18 days use 40 to 50 percent RH, then increase to 60 to 70 percent RH during the final lockdown period. Adjust hysteresis values based on your heating and cooling system response characteristics, typically 0.5 to 1 degree Celsius for stable control. Monitor the system for 24 hours to ensure the controller maintains setpoints within acceptable ranges, then proceed with egg placement. The controller will automatically cycle heating and humidification systems to maintain your configured parameters throughout the entire incubation period.

Frequently Asked Questions

What is the difference between the temperature and humidity control circuits in the XM-18?

The XM-18 features two independent relay circuits that operate simultaneously without interference. The temperature circuit uses a PID algorithm to regulate heating elements, cycling power on and off to maintain your setpoint temperature. The humidity circuit uses simple on-off relay switching to control humidifiers or dehumidifiers based on humidity readings. This dual-circuit architecture prevents the heating system from affecting humidity control and vice versa, resulting in more stable incubation conditions than single-circuit controllers where heating and humidification compete for control.

Can the XM-18 control both heating and cooling systems?

Yes, the XM-18 includes separate relay outputs for heating and cooling circuits. The heating relay activates when temperature falls below your setpoint minus the hysteresis value, while the cooling relay activates when temperature exceeds your setpoint plus the hysteresis value. This allows integration with both heating elements for cold environments and ventilation fans or cooling systems for hot environments, making the controller suitable for year-round incubation in various climates across India.

What sensor types are compatible with the XM-18 and how do I calibrate them?

The XM-18 uses an NTC thermistor temperature sensor with 10k ohm resistance at 25 degrees Celsius and a capacitive humidity sensor. Both sensors are pre-calibrated at the factory, but field calibration is possible through the menu interface. For temperature calibration, place the probe in a known-temperature environment like ice water at 0 degrees Celsius or boiling water at 100 degrees Celsius, then use the calibration menu to adjust the displayed value to match the known temperature. Humidity calibration requires saturated salt solutions at known RH levels, available in calibration kits. Recalibrate sensors annually or if readings drift more than 2 percent from known values.

What happens to my setpoint settings if there is a power failure?

The XM-18 uses non-volatile EEPROM memory to store all setpoint parameters, calibration values, hysteresis settings, and control preferences. If power is lost, the controller will retain all settings and resume operation exactly as configured when power is restored. The controller will not lose any data even if unpowered for extended periods. However, during the power outage the incubator temperature and humidity will drift based on ambient conditions, so it is recommended to use the controller with a backup power supply or uninterruptible power supply for critical hatchery operations.
