ATTENTION
A gas water heater depends on accurate temperature feedback to control heating performance. When the control board receives delayed or inaccurate temperature data, the appliance may respond slowly, produce unstable hot water, or experience temperature fluctuation during use.
The vangood High Efficiency Temperature Sensor is designed for compatible gas water heaters and related heating appliances. It works as a thermal feedback probe between the appliance heating area and the control board. By detecting temperature changes and transmitting the corresponding signal, the sensor helps the control system manage heating operation more accurately.
The product is available with two sensing element options:
- K Type Thermocouple
- NTC Thermistor
These two options use different signal principles and must be selected according to the control board design. A K Type thermocouple generates a millivolt signal according to temperature. An NTC thermistor changes resistance according to temperature. They are not interchangeable unless the control system has been specifically designed for both types.
The sensor is designed for a temperature range from 0°C to 150°C, with measurement accuracy of plus or minus 1.5°C and a response time of no more than 3 seconds. These specifications provide a practical thermal feedback solution for residential gas water heaters, heating appliances, and compatible boiler systems.
INTEREST
Dual Sensing Options for Different Control Boards
Different gas water heater control boards use different temperature sensing methods. Some systems calculate temperature through resistance changes from an NTC thermistor. Other systems use the millivolt output from a K Type thermocouple.
The vangood probe can be supplied in either configuration according to the customer’s control board. This provides greater flexibility for water heater brands, distributors, and OEM customers developing different product lines.
Before selecting the sensing element, the engineering team should confirm:
- Control board input type
- Required resistance or millivolt signal
- Temperature calculation method
- Connector and pin arrangement
- Sensor installation position
- Required cable length
Correct matching helps prevent inaccurate temperature readings, error codes, unstable burner control, and unnecessary replacement during assembly.
0°C to 150°C Temperature Range
The sensor is designed for a temperature range from 0°C to 150°C. This range supports temperature monitoring in compatible water heater heating zones and related appliance control applications.
A broad sensing range helps the control system monitor different operating conditions, including low-temperature standby conditions, normal hot water operation, and higher temperature areas near the heat exchanger or water outlet circuit.
The exact installation position is important. The probe should be installed in the location specified by the appliance design. A sensor installed too far from the measurement point may respond slowly, while a sensor installed in an unsuitable high-heat location may not provide the expected reading.
±1.5°C Measurement Accuracy
Temperature accuracy directly affects the user’s hot water experience. If the sensor reading is too high or too low, the control board may adjust the burner output incorrectly. This can lead to temperature variation, inefficient heating, or premature safety action.
With a measurement accuracy of ±1.5°C, the probe provides a precise feedback reference for compatible gas water heater control systems. The actual system performance also depends on control board calibration, sensor installation, water flow, burner response, gas pressure, and the complete appliance design.
For OEM customers, the sensor can be evaluated with the control board and water heater prototype to confirm the required temperature curve and control response.
Response Time of 3 Seconds or Less
A temperature probe must respond quickly when water temperature changes. A delayed signal may cause the burner to continue heating after the target temperature has changed, increasing the possibility of temperature overshoot.
The product provides a response time of 3 seconds or less according to the supplied specification. This helps the control board receive updated temperature information more quickly during changing water flow and heating conditions.
Response time depends on the sensing element, sheath construction, installation position, water movement, and test method. For final product evaluation, customers should confirm the response time under the actual appliance conditions.
304 Stainless Steel Protective Sheath
The probe uses a 304 stainless steel sheath to protect the sensing element. Stainless steel provides a durable protective structure for applications exposed to moisture, temperature changes, and normal water heater operating conditions.
The sheath also helps protect the internal sensing element during installation and maintenance. Its metal construction provides a practical balance between mechanical protection and thermal transfer.
The exact sheath diameter, insertion length, mounting thread, and connection structure should be confirmed according to the selected model. These dimensions are important when replacing an existing sensor or integrating the probe into a new water heater design.
High Temperature Silicone Cable
The standard cable uses high temperature silicone wire with a length of 1.5 meters. Silicone insulation helps the cable remain flexible in appliance wiring spaces exposed to elevated temperatures.
The 1.5m cable length can support common wall mounted water heater layouts. For larger appliances, special chassis designs, or control boards installed farther from the sensing point, customized cable length can be discussed.
Cable customization may include:
- Cable length
- Connector type
- Terminal arrangement
- Wire color
- Cable routing requirement
- Shielded cable option where required
The final cable specification should be confirmed according to the control board and appliance wiring design.
