Digital Temperature sensor – High Accuracy 0.7ºC         SMT-160-30
The Smartec digital temperature sensors are accurate to 0.7ºC from -30ºC to 100ºC and 1.2ºC from -45ºC to 130ºC. Output linear within 0.2ºC. The sensor is a three terminal device with integrated sensor circuitry. A duty cycle modulated square wave is available from one terminal, the other two being power input and ground. The single-wire interface makes it simple to interface with any micro controller.

Digital Temperature sensor – Evaluation kit                         SMT-SA04
This small evaluation board can be connected directly to a computer through the RS232 serial port. The RS232 port powers the sensors, no external power supply is needed. Up to 4 sensors can be monitored simultaneously. Long cable lengths up to 20 metres.

Temperature Acquisition System - Up to 8 sensors           SMT-AS08
The SMTSA08 is specially developed for engineers who need to accurately monitor multiple temperatures but do not want to develop their own hardware. The 8 channel temperature measurement system is based on the use of the Smartec digital temperature sensors SMT160. The RS232 interface offers fast serial communication to a data logger or personal computer. Long cable lengths.

Pressure  sensors                                                                         SMT-SPD
Pressure ranges available from 0 – 6.5 Bar. Absolute or Gauge type. The gauge type contains a reference vacuum chamber on the die. The sensors are silicon based and encapsulated in modified plastic. The gauge sensors are available in six pin DIL packages and the absolute sensors are SMD. Medical, barometric, automotive applications. Easy interface to the Smartec Universal Transducer Interface (UTI)

Infrared non-contact temperature sensor                    SMT-IR9901/02
The Smartec infrared sensors are sophisticated full silicon thermopile sensors. The sensors are particular suited for non-contact  measurement of surface temperature by monitoring heat radiated from the surface. High Accuracy. Low cost. Fast response time of 40mS.  The IR9902 has a built in temperature sensor.                  Typical applications:  Temperature measurement on moving objects, medical, climate and gas analysis

Humidity                                                                                           SMT-HE10
The Smartec humidity sensor, unlike others, measures RH from 0 to 100% without any reduction in performance. Its construction means that it is not affected by temperature or pressure. The sensor is a two terminal capacitor, which increases in value as water molecules are absorbed into its active polymer dielectric.  High accuracy. Linear from 0 – 100% RH. Reliable construction & long-term stability. 

Universal Transducer Interface                                                   SMT-UTI
The UTI is a smart interface for analogue sensors such as capacitive sensors, platinum resistors Pt100, Pt1000, Thermistors, resistive bridges and potentiometers. Ideal for use in micro controller based systems. No need for A-D converter. One line output. Accuracy and resolution 14 bits. Measurement of multiple sensors. Automatic calibration. 2/3/4 wire measurement possible. 16 different modes.

Universal Transducer Interface – Evaluation board         SMT-UTIPCB
The UTI development kit is especially designed for quick set-up and easy design with the Smartec UTI. The small board can be connected directly to a PC via the RS232 port. All 16 modes of the UTI can be chosen remotely to demonstrate how easy it is to connect any type of sensor to the UTI. Data can be read via a terminal program. Labview program example included.
