Differential Pressure Gauge
DG12
This differential pressure gauge is sealed, Bourdon tube interior is terminal of high-pressure, and the casing interior is terminal low-pressure. It is small size, though bourdon tube deforms to detect differential pressure.
Features:
Sensing element is mainly used in air, nitrogen, non-corrosive gases for differential pressure detection. It is small size, light weight, easy installation.
DG16/17
These differential pressure gauges are compactly designed to measure the pressure difference (differential pressure) of two points.
They can also be used to measure tank liquid level, loss of head of strainers, or combined with an orifice to measure the flow of a pipeline.
These differential pressure gauges with electric contacts use a micro switch for ON-OFF control.
Features:
-Liquid filled inside the element allows them to withstand high pressure. The gauge is not damaged even by the excessive pressure or reverse pressure produced by valve operation.
-Top or bottom process piping connection can be freely selected by renewing the vent plug.
DG55/57 DG56/58(with electric contacts)
This pressure gauge is for checking the pressure difference between two points (differential pressure) and can be applied not only for checking differential pressure but also for checking liquid level and flow rate. A pressure gauge with contactors is equipped with a contact switch, being able to use for warning and controlling through relays.
Features
-The graduation of the differential pressure indicating portion is large, making reading easier.
-As the low differential pressure and high differential pressure type, this pressure gauge is highly reliable.
-The base pressure refers to the pressure to be used as the basis out of pressures at two points, or a pressure with smaller fluctuation. One-sided pressure tight means the maximum differential pressure
DG82
This is a minute differential pressure gauge with high reliability, equipped with magnetic couplings as the expanding mechanism. This pressure gauge is used to detect the pressure difference due to pressure loss in air filters of air conditioners for checking and controlling the clogged conditions of air filters. This pressure gauge can also be applied for checking and controlling interior pressure of clean and bioclean rooms. Additionally, this pressure gauge can be used as a micro pressure gauge by opening its low pressure side to the atmosphere.
Features:
+A diaphragm used as a differential pressure element is protected from excessive deformation by a backup plate.
+For both expanding mechanism and contact point mechanism, contact-free design has been adopted as far as possible, to obtain high sensibility and high reliability. Contact-free expanding mechanism without linkage mechanism is also adopted.
+A setting pointer is provided on the indicator dial. Its setting knob is installed in front of the pressure gauge, making the setting work easier.(for DG82 type only)
+This gauge is of small and lightweight type
DG85
This is a differential pressure gauge to detect the differential pressure, etc. due to the pressure loses of an air conditioning filter, being applied to extremely low pressure measuring.
This is a high-precision differential pressure gauge applied not only to minute differential pressure gauge application but flow meter and minute differential pressure gauge application.
Features
-Small hysteresis silicone rubber is applied to the diaphragm.
-This pressure gauge is of high pressure resistance type.
-Zero adjustment from the outside is possible.
-In the case of the wall type pressure gauges, by exchanging the right with the left of the volute fitting the connection of the high pressure side and the low pressure side can be inverted.
-RoHS directive compatible.
DG87
This is a differential pressure gauge to detect the differential pressure, etc. due to the pressure loses of an air conditioning filter, being applied to extremely low pressure measuring. Because of the edgewise type, reading is easy, this pressure gauge can be applied as a flow meter and a micro pressure gauge other than a micro pressure differential pressure gauge.
Features
-This pressure gauge indication is easy to read and pressure gauge itself is easy to use.
-This pressure gauge is provided with wider pressure measuring ranges. When anticorrosion is required, we are pleased to comply with such requirements.
-Small hysteresis silicone rubber is applied to the diaphragm.
-The special linkage mechanism is applied to the magnifying mechanism and the move transmitting mechanism, demonstrating high vibration resistance and durability.
-Even when the differential pressure becomes excessive, the safety mechanism has been applied to avoid damage to the moving portions.
-Zero adjustment from the outside is possible.
-This gauge is of small and light weight type.
-RoHS directive compatible.
DG93
This pressure gauge has been developed to measure a low differential pressure range of 4 kPa (400 mm H2O) or smaller. By not simply measuring differential pressure but displacing the measured differential pressure with various units, this pressure gauge can be applied to measuring a liquid level and a flow rate.
Features
-This is a differential pressure gauge for minute differential pressure, demonstrating excellent corrosion resistance by equipping a stainless steel bellows for the pressure sensing portion.
-Equipped with a 270degrees graduations dial, easy reading is possible.
-Even measuring minute differential pressure, the precision of +-1.5% of the full scale has been maintained.
-As standard specifications, this pressure gauge is equipped with an air vent.
-To make pressure piping easier, two direction pressure connections, the upper and the lower, have been provided.
DG95/96/97/98
These are compact pressure gauges which measure the pressure difference (differential pressure) between two points. They can also be used to measure liquid level and flow, as well differential pressure.
The pressure gauge with contacts uses a reed switch for warning and control applications.
Features:
+Pressure piping can be connected to either the up or down direction, so pressure piping work easy.
+Because a reed switch is used ,the contacts are not affected by the environment, resulting in long life and high reliability.
