Digital Solutions from Dexter
Dexter Research Center’s Digital Detectors and Temperature Sensor Modules (TSM’s) are based on our superior silicon thermopile technology and incorporate an ASIC that provides a cost-effective front end for reading out the detector output. The digital solutions include pre-amplification, A/D, multiplexing and SMBus communications. Additionally, the SMBus can accommodate communications with up to 100 digital products. Our digital solutions are housed in industry standard TO-5/TO-39 packages. They are available in a 5V device as well as in a 3V configuration that is ideal for the low power demands of battery powered applications.
Digital Detectors
The onboard ASIC in Dexter’s Digital Detectors provides for easy system integration and design. Ideal for gas detection applications such as environmental and indoor air quality monitoring.

Integrated Temperature Measurement Solutions
Temperature Sensor Modules
Dexter’s Temperature Sensor Modules (TSM’s) are ready-to use, cost-effective, non-contact IR thermometers. Factory calibrated output provides accurate object temperature sensing. You can customize this unit to accommodate a wide range of temperatures, power supplies, refresh rates and object emissivity. High memory reliability is assured by our TSM’s embedded error checking and correction mechanism.
Dexter’s TSM is ideally suited for handheld portable applications thanks to its low power consumption and sleep mode. Our digital sensor interface offers you a choice of a power-up-and-measure PWM or an enhanced access SMBus compatible protocol. Just two signal lines can accommodate systems with up to 100 modules. A wide variety of freezing/boiling prevention and alert systems are made possible thanks to a built-in thermal relay function.
