Product Specifications: H11706-40

Category	Specification	Details / Interpretation
General Information	Model / Part Number	H11706-40
	Product Type	Bourdon Tube Pressure Gauge (Analog Dial Indicator)
	Brand	Commonly associated with WIKA or similar instrumentation brands.
Performance	Pressure Type	Gauge Pressure (relative to atmospheric pressure)
	Pressure Range	The “-40” suffix definitively specifies the range. It is an industry standard for a range of 0 to 40 bar. (This is a common higher-pressure range for industrial hydraulic systems, compressed air systems, and process applications using metric units. Equivalent to approx. 0-580 psi.)
	Accuracy	Typically Class 1.0 (±1% of full scale) or Class 0.5 (±0.5% of full scale). The large dial allows for precise reading even at higher pressures.
	Dial Size	Likely 160 mm (6.3″) diameter. The “17” prefix indicates this large, panel-mounted size.
Connection & Mounting	Process Connection	Likely Lower Mount (Bottom Entry). Often includes a rear flange for stability.
	Connection Size & Thread	Likely ½” NPT or G½” BSP Male. Robust connection required for higher pressures.
	Material (Connection)	Cannot be determined from “-40”. This suffix defines range, not material. The base “H11706” model likely has a default material, which is often stainless steel for higher pressure ratings.
Materials	Case / Housing	Often Stainless Steel (e.g., 304SS) for durability and strength at higher pressures.
	Window	Laminated Safety Glass
	Movement / Internals	Likely Stainless Steel for strength and compatibility with higher pressures.
	Bourdon Tube	Stainless Steel (316 SS). A robust tube material is essential for the 40 bar pressure range.
	Seals	FKM/Viton® or PTFE, suitable for higher pressure applications and a range of media.
Environmental	Operating Temperature	Ambient: -20°C to +60°C (-4°F to +140°F) Media: Max. +100°C (+212°F)
	Pressure Limit	Safe Working Pressure: Up to 40 bar (100% of range). Overload Safety: Typically 52 bar (130% of range). The construction is robust for these pressures.
	Filling	Often liquid-filled (e.g., glycerin) to dampen vibration and pulsation, which is critical for readability and longevity in high-pressure systems.
	Protection Class	IP65 or higher.
