BA100电子气压计钓鱼爱好者都知道大气压力对鱼的活性有影响，主要是高气压情况下，水里面的溶氧量就高，鱼儿的活性高胃口就好；反之，鱼的活性很低，胃口就差。
如果了解气压变化情况，对于提高鱼获几率将会有很大帮助。
您想知道在什么气压情况下去钓鱼吗？ 该款电子气压计就是为钓鱼爱好者提高鱼获几率而设计的一款产品。
该产品主要功能有气压测量、高度测量、温度测量、6组钓点气压记录、钓点水深记录、钓点气压校正、适合钓鱼气压报警功能设置、天气预报、24小时气压变化图表显示、历史3天数据记录、时间日期、LED 蓝色背光等。
特点：1．一键校正钓点气压功能，让您无论何时何地都可以掌握钓点准确的气压信息，为出钓之前提供依据。
说明：气压变化及天气变化在一定区域范围内可以默认为线性变化（约100－200公里范围）。
基于此，该项功能可正常使用。
例如，在钓点1位置（西丽水库）保存该位置气压值1006.2hpa；回到家中（20楼）气压999.3hpa,校正钓点1气压值，把家里的气压变化与钓点气压形成联动关系。
当家里气压变化2hpa 时(即1001.3hpa)，钓点1对应变化2hpa(即1008.2hpa)；同时形成24小时气压变化图，为出钓之前提供准确的气压参考依据。
可跟踪6个钓点气压。
（具体参考1－3步骤）2．开放钓点气压数据记录功能，您可根据需要记录钓点的水深，气压值等。
为您的下一次出钓提供参考。
说明：例如，再钓点1，气压1012hpa,水深2米，钓得一重达5斤的大物。
把该气压值及钓位水深2米保存，以备下次在该钓位作参考。
（见2、3项步骤）。
3． 24小时气压变化图，气压变化趋势箭头指示，让您时刻掌握气压变化情况，适时调整钓位水深，提高鱼获几率。
说明：在夏天钓鱼，一天里面的气压变化往往很剧烈，反应在鱼身上就是表层活动的鱼有时会浮头，底层活动的鱼也会跑到水的中上层活动。
这个时候如果还采用钓底的方式钓鱼，往往会空手而归，如果适时调整钓位的水深，可能会有意想不到的收获。

The TEXAM eis the new electronic version of the TEXAM pressuremeter in which the pressure and deformation are measured with electrical sensors and read with a tablet -operated readout.EASY TO OPERATE PRESSUREMETERREAL TIME READING AND PLOTTING OF TEST RESULTS RUGGED CONSTRUCTION∙ Electronic version of the TEXAM∙ Easy to operate and maintain ∙ Rugged construction∙ Controlled rate of deformation or pressure ∙ Conforms ASTM D4719-07 ∙ Safe : no compressed gas necessary ∙ Versatile: Easy cyclic or creep testing∙Automatic acquisition & real time visualisation for enhanced control of the test on an Android tablet*Key FeaturesDescriptionThe TEXAM epre -boring pressuremeter is a rugged and reliable instrument that can be used for various ground engineering applica-tions. This pressuremeter distinguishes itself by its ease of use and versatility. Loading is done manually with a screw jack, which allows the user to run tests in either strain or stress controlled steps. The manually -controlled hydraulic loading system ensures a good re-peatability of the test, while making unload -reload cycles very easy. The new electronic version of the TEXAM pressuremeter makes general operation of the equipment even easier and repeatable.This equipment includes the following parts.A control unit houses electrical pressure and volume sensors, con-nectors, a control valve and a manual actuator (screw jack) for pres-surizing the water in the cylinder via a piston.A readout unit consists of the DP Box unit operated with an Andoid tablet. This versatile readout is compatible with other pressure-meters manufactured by Roctest. A special application, installed on the tablet, allows configuring the tests and calibrations, to read and plot the test results in real -time, to log the data, and to review test results.A water -filled probe is fitted with an easy -to -replace single outer sheath. This sheath consists of rubber typically protected with metal-lic fins.And finally an easy -to -repair, high -pressure tubing connects the probe to the control unit.TEXAM e - Pressuremeter∙ Bearing capacity and settlement estimation of alltypes of foundations∙ Deformation of laterally loaded piles and sheet pilesApplicationsPlease specify:∙ Tubing length (25, 33 , or 50 m) ∙ Probe diameter∙ Accessories (metallic sheaths, rings) and optional itemsSpecificationsRoctest Ltd, 680 Birch Street St -Lambert, Quebec Canada J4P 2N3Phone +1 450 465 1113 Fax. +1 450 465 1938 ********************* Web Roctest reserves the right to make any changes in the specifications without prior noticeE5001E -180202Control unitWorking pressure 10 000 kPa (1500 psi) Dimensions40 x 46 x 125 cm (l x w x h) as-sembledWeight30 kg / 28 kg (Box / Actuator) D/P BOX Readout unitUser Interface Bluetooth communication with an Android tablet Resolution 1 kPa and 0.01 cm 3 Power Supply 2 x 12 V, 2.3 A, rechargeable batteriesDimensions 25 x 28 x 12 cm (l x w x h)Housing Splashproof, resistant ABS case Autonomy> 8 hours typicallyPower supply interfaceUniversal AC wall plug with US/Euro adapter + adapter cable for car (lighter) & for external batteryProbeDiameter 74 mm (N Long) / 44 mm (A) Length 72 cm / 84 cm Weight6.4 kg / 4.5 kg Max radial expansion35 %Test ProcedureThe probe is placed at the test depth in a pre -drilled borehole obtained by a method adapted to the soil conditions: wet rotary drilling, auger-ing, shelby tube pushing, etc. In granular soils below the water table, the probe can be driven directly within a slotted cas ing.

Principles of OperationMost Trerice Pressure Gauges are constructed with a bourdon tube sensing element. When the sensing element is subjected to pressure, it flexes and the resulting motion is transmitted as a measurement through a mechanical movement to the dial face pointer.Pressure GaugesDESIGN & OPERATIONSelecting a Pressure GaugeCaseCases are available in a wide variety of materials andconfigurations. The combination of material and configuration is generally determined by the demands of the application, as well as the preferences of the gauge specifier. The moredemanding the environment, the more rugged the case construction (i.e., polypropylene or stainless steel for industrial applications vs. aluminum or steel for construction or commercial applications).Gauge mounting or retrofitting needs may affect case selection (i.e., a gauge to be panel mounted will require either a front flange or u-clamp style case). For safety considerations, a “solid-front”case style may be required. Each application will have a unique set of requirements which will help guide the specifier in selecting the appropriate case style.Wetted Parts and Pressure MediumUnder normal operating conditions, only the tube and socket assembly (Wetted Parts) of a pressure gauge will come into contact with the fluid being measured (Pressure Medium). The selection of the assembly will be determined by the composition of the medium. Air, gas, steam, water and other non-corrosive media are usually satisfied by a bronze or brass bourdon tube and brass socket assembly. Stainless steel or Monel wetted parts are used when the medium contains corrosive elements or when high operating pressures or temperatures will be encountered. A diaphragm seal is recommended for highly corrosive media or that which may solidify or depositsolids within the tube and socket assembly of the gauge. (See the Diaphragm Seal section of this catalog.)CASEBLOW-OUT BACK DIAPHRAGMBOURDON TUBEMOVEMENTSOLID CASE FRONT DIALPOINTERRINGWINDOWSEALSOCKETConnection and MountingThe socket connection provides an entrance port for the process medium as well as a means to mount the gauge to a pipeline or vessel. Male connections can be provided with NPT, BSPT, or other thread styles, in sizes from 1/8" through 1/2". A high-pressure, 9/16" LHT connection is also available. The mounting location indicates where the connection protrudes from the case. Trerice Pressure Gauges are available with three standard mounting locations: lower male (LM), lower back male (LBM), and center back male (CBM). Other connection locations may be available on some models.Window and RingThe window provides a means for viewing the measurement, as well as protection of the dial face and pointer of the instrument, and is normally held in place by a ring, which is screwed or snapped to the case of the gauge. Plastic, clear glass and laminated glass are common window materials. Ring styles include threaded, bayonet, friction, crimped and hinged, depending upon the case type. PointerThere are essentially three types of pointers available on Trerice Pressure Gauges: a micro-adjustable pointer (providing high quality and accuracy); a friction-type pointer (providing adjustability and durability); and a plain, non-adjustable pointer (providing economic reliability). AccuracyThe accuracy of a pressure gauge is expressed as a percentage (plus or minus) of the maximum scale range. Please refer to Pressure Gauge Standard ASME B40.100.Liquid FillingLiquid filling (glycerin, silicone or other fills) can prolong the life of a pressuregauge by minimizing wear on the gauge internal resulting from vibration or oscillation. Liquid filling also acts as a permanent lubricant to the moving partsof the instrument.。
