HYODA INSTRUMENTS CORPORATION17耐圧防爆構造とは全閉構造で容器内部で爆発性ガスが爆発した場合でも、その爆発圧力に耐え、且つ外部の爆発性ガスに引火する恐れのない構造をいいます。これに基づき製作された圧力スイッチ及び差圧スイッチは工場、その他の事業所において可燃性ガスまたは引火点40℃以下の可燃性液体の蒸気の存在する恐れのある場所での圧力の測定、警報、制御にと幅広くご使用頂いております。The pressure-resistant and explosion-proof frame is wholeclosed structure which is endurable to the explosivepressure also is not quite ignited external explosive gases incase of exploding in a vessel. The pressure switch and thedifferential pressure switch were manufactured due to beingbased on the rules are widely used for pressuremeasurement, alarm and control in which plants or otherplaces of business probably exist ignitable liquid vapor atignition point of below 40 ℃or ignitable gases.□電気接点付圧力計Pressure Gauge with Electric Contactこの圧力計の接点は低接触圧で作動し、ブザー、ランプの点滅等の警報用に使用されます。リレーを用いると用途は更に拡大します。The contact switch in this pressure gauge works byextremely low contact pressure and is used for alarm ofturning buzzer, lamp etc. on and off. Concurrently, itbecomes wide application more to use with a relay together.（3）警報接点付圧力計Pressure Gauge with Electric warning Contact□コンタクト接点付圧力計Pressure Gauge with Pointer Contact■耐圧防爆形圧力スイッチExplosion-Proof Type Pressure Switch■仕様0－5 KPa〜0－30 KPa1又は21 or 2単極双投S.P.D.T.フルスケールの最大5％Max.5% of F.S.抵抗負荷Non-inductiveLoad（Resistance Load）AC200V-10ADC100V-0.4A銀色アルミ合金Silver colorAluminiumAlloyマイクロスイッチMicroswitch0－0.06 MPa〜0－60 MPa圧力範囲Pressure RangeチャンバーChamberブルドン管Bourdon tubeエレメントElement黄銅又はステンレス鋼（SUS316）Brass or Stainless steel (SUS316) ステンレス鋼（SUS316）Stainless steel(SUS316) 接液部材質Wetted partsMaterial接点種別Kind of Contact接点数Nos. ofContact内部調節InternalType設定方法Setting接点応差Differential接点容量CapacityケースCase■耐圧防爆形差圧スイッチExplosion-Proof Type Differential Pressure Switch0－0.01MPa〜0－0.06MPa1又は21 or 2フルスケールの最大10％Max.10% of F.S.抵抗負荷Non-inductiveLoad（Resistance Load）AC125V-5ADC30V-3A銀色アルミ合金Silver colorAluminiumAlloyマイクロスイッチMicroswitch差圧範囲Differential Pressure RangeベローズBellowsエレメントElementステンレス鋼（SUS316）＋NBRStainless steel(SUS316) ＋NBR接液部材質Wetted partsMaterial接点種別Kind of Contact接点数Nos. ofContact内部調節InternalType設定方法Setting接点応差Differential接点容量CapacityケースCase注）1. 1接点の場合は差圧指示付2. 2接点の場合は差圧指示なし3. 耐圧は5MPa以内ですNote) 1.
