Caution in Thermistor Sensor Usage
Due to the possibilities of destruction of the sensor, damage or misuse of equipment, please strictly follow below matters:
- The sensor is designed for individual usage. When it is going to be used beyond the specified condition, please speak to your daily contact person for our products.
- Whenever designing the equipment, make sure to check sensor operation and if there is no lack of quality.
- Do not use the sensor exceeding rated electric power.
- Due to possibility of causing the decrease of the value of resistance with self-heat and malfunction of the equipment or the precision decrease of the inspection temperature, carefully refer to the dissipation constant, usage of electric power and voltage.
- Do not use the sensor beyond operating temperature range.
- Avoid from exceeding radical temperature change, which is beyond operating temperature range.
- If the sensor is used as the main control of the device, be sure to take safety measures such as providing a safety circuit and parallel use with another similar function sensor, to prevent accidents.
- Under the environment which receives the influence of electric noise, make sure to take countermeasure by installing a protection circuit and seal the sensor including the lead wire.
- Do not add excessive vibrating, shocking, pressure.
- Avoid from excessive pulling and bending of the lead wire.
- Do not impress excessive voltage in the insulated part and between the electrode; this might cause the insulated malfunction.
- Do not use in corrosiveness gas atmosphere (CO2, NH3, SO2, NO2) beyond the designated condition. Do not use at the place where the sensor touches the electrolytic brine, acid, alkaline and/or organic solvent beyond the designated condition.
- When you do processing such as resin molding by using thermistor sensor, please be reminded that sensor might be destroyed by the material or mismatches of it. If there is any others unclear point, please inquire to our company sales in charge.
