Crystal sensor
Three main groups of materials are used for piezoelectric sensors: piezoelectric ceramics, single crystal materials and thin film piezoelectric materials. The ceramic materials (such as PZT ceramic) have a piezoelectric constant/sensitivity that is roughly two orders of magnitude higher than those of the natural single crystal materials and can be produced by inexpensive sintering processes. The piezoeffect in piezoceramics is "trained", so their high sensitivity degrades over time. This d… WebCharacteristics are a wide temperature range. Standard temperature range is -50 to +100°C with optional extended range to +180 or +370°. The Piezoelectric Resonator Sensor withstand high shock and vibration. …

WebP-type metal oxide semiconductor with extraordinary surface reactions is highly active for gas sensing reactions. However, presenting large active sites in materials surface for sensing reactions is a great challenge. Here, we report a strategy to fabricate Co3O4 hexagonal platelets and characterize the adsorption of ammonia (NH3) by using density … WebStandard unit has 2 crystal sensor inputs and 2 isolated rate control analog output drivers, expandable to 4 each. 8 relay isolated outputs and 8 optically isolated inputs (active or passive mode), with the option to upgrade to 32 ea., for ancillary operations such as pocket indexing, sweep selection and sensor selection.
