The intrinsically safe instrument is totally non-intrusive and with minimal test surface preparation, and no consumables such as grease required, reliable measurements can be made within a minute. Measurements can be taken from small pipes and large vessels, at any orientation and at any temperature up to 500 °C (932 °F), with a single probe. Portable ozone (O3) meter GfG The MICRO III, with its small dimensions of only 4,7 x 8,8 x 2,5 cm, is the ideal gas detector for personal protection. The single gas detector with ATEX certification weighs only 75 g. It detects reliably oxygen, hydrogen or many toxic gases like hydrogen sulphide, ammonia, ozone, carbon monoxide, etc. The current gas concentration is shown on a large display. With a loud alarm of 95 dB and a changing frequency the small single gas detector is audible even in noisy environments. Simultaneously, two bright and alternately flashing LEDs indicate a gas alarm. Three alarm levels and the battery alarm provide comprehensive protection. With a permanent operation of 24 hours a day a single AA battery powers this instrument for up to 9 months. The long-life smart sensors allow the change to other gases without any problems, since the detector recognizes the new sensor type. A high-performance pump (as per ATEX) for gas sampling can be easily attached, ensuring to detect gas hazards in confined areas. Gases to be detected: O2, H2S, CO, NO, NH3, HCN, HCl, SO2, H2, C2H4O, SiH4, PH3, COCl2, NO2, Cl2, O3, ClO2. ... see all the products in the category    Gas analyzers, Portable gas detectors 14 products in   Temperature sensors Sensor for surface temperature measurement MINCO Install these compact sensors anywhere for accurate point sensing and fast response.

In such case American are preferred for their accuracy and long term stability These sensors are frequently welded at the end of leads or cables, with or without a shield, depending of use. Sensor for surface temperature measurement Betatherm The Ni1000SOT is a nickel thin film resistance temperature detector (RTD) that is suitble for use in contact temperature sensing. The characteristics of the temperature sensor comply with DIN 43760. The Ni1000SOT is manufactured by PVD-depositon on a silicon substrate. The thin film structure is covered by a passivation layer for environmental protection and enhanced stability. The nickel elements are mounted on lead frames and encapsulated in SOT23 packages. This technology allows the production of miniature, low cost, high precision temperature sensors. The Ni1000SOT sensor is qualified for the most demanding automotive applications (including exposure to hot oil) and is suitable for many more applications in harsh environments.

Both companies specialize in negative temperature co-efficient (NTC) thermistors for precision temperature measurement in environments where there is a high cost of failure. Thermistor-based temperature sensors exhibit a change in their electrical resistance in response to a change in ambient temperature conditions. They are highly-sensitive and have very reproducible resistance-versus-temperature properties. Thermistors can be further classified as either “Positive Temperature Co-efficient” (PTC thermistors) or “Negative Temperature Co-efficient” (NTC thermistors). Both PTC and NTC thermistors have distinct features and advantages that make them ideal for different end-use sensor applications. Whereas PTC thermistors demonstrate an increase in resistance when subjected to an increase in temperature, NTC thermistors demonstrate a decrease and are commonly used for more accurate temperature sensing. This accuracy makes them unique in their functionality in many applications compared to other temperature sensors/switches such as thermocouples or electromechanical thermostats, which they are steadily replacing. NTC thermistors are available in a wide variety of configurations and protective coatings to suit almost any application. The particular features and advantages of NTC thermistors compared to other sensor types include: Large temperature sensitivity and broad range of function Available in many physical forms and not constrained by material types Interchangeable devices eliminate need for individual sensor calibrations Good electrical noise immunity Easy to interface to electronic instrumentation Can be customized to optimize thermal response requirements NTC thermistors are the most versatile and cost-effective temperature sensors in terms of satisfying typical selection criteria and in their inherent advantages over other sensor types. Web-based temperature transmitter Measurement Computing Measurement Computing Corporation, a market leader in low-cost data acquisition, has announced the release of two Web-enabled temperature input devices, the WEB-TEMP and the WEB-TC, which allow users to take measurements and monitor them via the Internet. The new products, modeled after MCC’s popular USB-TEMP and the USB-TC products, have corresponding performance, but are Ethernet compatible with built-in Web servers that write temperature data to their own Web page for immediate Internet access from virtually everywhere! The WEB-TEMP provides eight temperature input channels, each supporting all of the common temperature sensors (J, K, R, S, T, N, E, and B thermocouples; 2-, 3-, or 4-wire RTDs; thermistors, and semiconductor temperature sensors), and 8 bits of digital I/O. Each channel of the WEB-TEMP is capable of monitoring any of the supported input types, so users can mix and match the sensor to the measurement without additional signal conditioning. Moreover, the internal measurement electronics accuracy of the WEB-TEMP vastly exceeds the accuracy specifications of the temperature sensors, thereby recording the most accurate data possible. The WEB-TC specifications are similar to those of the WEB-TEMP, but support thermocouple sensors only. All eight WEB-TEMP (or WEB-TC) inputs have 500 VDC isolation to the power supply and Ethernet port, protecting both the computer and the input device from damage. The WEB-TEMP and WEB-TC ship with an impressive array of software included in the MCC DAQ Software CD. The disk includes applications, drivers, and libraries that meet the needs of programmers and nonprogrammers alike.

Ultrasonic transducer MSI Sensors Piezoelectric film ultrasound transmitters and receivers offer unique advantages for air ranging applications. Resonance frequency and vertical beam directivity of the transmitter and receiver can easily be customized by changing the diameter and length of the PVDF cylinder. Cylindrical PVDF receivers exhibit very wide horizontal or omni-directional beam directivity and broad band characteristics. These characteristics lend unique solutions in many applications such as two-dimensional positioning, digitizer, object detection, and distance measurement. Piezo film ultrasound transducers also have very low resonance "Q" values. This means that the signal rise and decay times are much shorter than conventional ceramic ultrasound transducers, making Piezo film transducers ideal for positioning applications. ... see all the products in the category    Acoustic sensors 4 products in   Indicators, Displays Electronic measuring display SIKO SIKO electronic displays are freely prgrammable via robust, front-sided membrane keyboard ensuring an easy and flexible adaptation for displaying different measured values.
