Product Specifications: H11900-04

Category	Specification	Details / Interpretation
General Information	Model / Part Number	H11900-04
	Product Type	Digital Pressure Gauge or Pressure Transmitter (Highly Likely)
	Brand	Commonly associated with WIKA or similar instrumentation brands.
Performance	Pressure Type	Gauge Pressure (relative to atmospheric pressure). Other types are possible.
	Pressure Range	Unknown. Must be confirmed. The “1900” series encompasses many ranges. The “-04” may not directly indicate the range.
	Output Signal	The “-04” suffix is a strong indicator of the output type. In many coding systems, this specifies a 4…20 mA analog output signal (2-wire loop powered). This is the most likely meaning.
	Power Supply	10…30 V DC (Standard for 2-wire 4-20mA transmitters).
	Accuracy	Typically higher than analog gauges, e.g., ±0.5% of full scale (FS) or better.
	Display	If a digital gauge, may include an LCD to display pressure values.
Connection & Mounting	Process Connection	Likely a standard thread such as ½” NPT or G½” BSP.
	Electrical Connection	Likely a M12 x 1 4-pin connector, or a cable gland for direct wiring.
	Material (Connection)	Cannot be determined from “-04” alone. The base model likely has a default, often Stainless Steel.
Materials	Case / Housing	Often Stainless Steel (e.g., 304SS).
	Wetted Parts	Likely Stainless Steel (316 SS) for the pressure sensor and connection.
	Seals	FKM/Viton® or PTFE, suitable for various media.
Environmental	Operating Temperature	Electronics: -10°C to +70°C (14°F to 158°F) Media: Max. +100°C (+212°F)
	Protection Class	Typically IP65 or IP67 (Dust-tight and protected against water).
	Certifications	May include CE, RoHS. Potentially ATEX/IECEx for hazardous areas.
