The TG1000 is a water cooled heat flux sensor with 10mV full scale output.
TG1000 range of Water cooled circular foil heat flux gages are designed for applications with longer measurement times. The water removes the absorbed heat continuously. All Thermogage heat flux sensors have a maximum operating temperature of 200°C regardless of heat flux applied. When water cooling these sensors, it is not recommended to connect sensors together in series due to pressure drops.
The Thermogage sensor is designed to provide an approx output signal of 10 mV when exposed to the specified heat flux range. The sensor can be exposed to approx 50% higher heat flux and still provide a good output signal. The gage looses the linear output when exposed to heat flux levels above 50% stated heat flux range. Damage to the sensor occurs when the sensor is exposed to heat flux levels above 100% of specified heat flux range.
The TG1000 is built to order and therefore the heat flux range for full output (10mV) must be specified by the customer.
Using an amplifier with the Thermogage product allows for fast time response in lower ranges. See amplifier information. AMP11 is a suitable amplifier with a gain of up to 1000.
Transducer Calibration Accuracy: +/-3% of full scale
Sensitivity: Up to 2 mV/(W/cm²)
The factory applied base coat is high temperature black paint. It is selected for temperature stability and flat spectral absorbancy. It has an emissivity of 0.86. Other coating options include colloidal graphite, black velvet, and soot.
All transducers are designed for 10mV maximum output. Units may be overdriven to 15mV without damage or loss of calibration. Overdriving beyond 20mV will, however, damage the guage.
A continuous x-y calibration curve graph and NIST traceable calibration certificate are furnished with each transducer.
This product is shipped in bubble wrap plastic bag, approx 20cm x 19cm x 1cm (LWH) weighing typically 165gms (dependant on sensor body)
