Whether looking at a low heat flux level, pushing a signal through a long cable length, or even just for signal processing convenience, a signal conditioning amplifier can make the difference between a mediocre signal and solid data. Vatell provides a number of amplifiers designed to work with our sensors. We can also provide signal transmitters and panel meters for ease of use.
Dual Channel HFM Amplifiers
These amps are designed to boost the signal of both the heat flux and temperature outputs from our thin-film heat flux sensor the HFM, having one channel for each. Each channel has an independent gain and an output voltage range of up to 5V. For the HFM-6 and HFM-7 which have resistance temperature sensors, the Vatell amplifiers include a calibrated current source for interrogation so that the output is a user-friendly voltage signal.
Single Channel Amplifiers
The AMP-15 is primarily designed to work with our Thermogage sensors, but can be used with any single output Vatell sensor. Normally the AMP-15 and Thermogage are calibrated as a pair, but separate sensor and amplifier calibrations are available if requested. The typical use is to provide a good sensitivity for low range applications but with a fast time response. The AMP-15 can also provide a voltage boost for data acquisition systems that need more signal than the nominal 10mV range of the Thermogage.

Tranmitters and Panel Meters
A digital readout or an alternate signal type is sometimes required. For those applications Vatell will pair a heat flux sensor with a calibrated Texmate digital panel meter or a Moore Industries signal transmitter. Ask our sales department for more details.
