ZHSYMX Digital Oil Pressure Gauge 52mm (2-1/16") 0–150 PSI with Large LED & Programmable Alerts

The ZHSYMX Universal Oil Pressure Gauge Kit is a 52mm (2-1/16") digital oil-pressure meter that displays 0–150 PSI with a bright center LED, sweeping LED needle, and user-programmable warnings.

This compact kit gives drivers a clear, configurable readout of engine oil pressure so you can spot abnormal pressure changes quickly. Built for both cars and trucks, the gauge combines a precise 0–150 PSI sensor with a slim dash-mounting design, selectable alert thresholds, and a large central LED so readings are visible day or night.

How accurate is the ZHSYMX oil pressure reading?

The system uses a dedicated pressure sensor with a 0–150 PSI measurement range and a threaded NPT 1/8" mounting for reliable installation. The electronics support stable, repeatable readings suitable for monitoring normal engine operation and troubleshooting pressure-related issues.

• Measurement range: 0–150 PSI for broad coverage of light- and heavy-duty vehicles
• Sensor thread: NPT 1/8" for standard fittings and adapters
• Powered by 12V or 24V DC with low draw (max 0.3A)
• Designed for consistent readings during idle and load conditions

What display and interface features improve visibility and control?

The gauge pairs a large center LED numeric display with a sweeping red LED “needle” around the face for instant visual reference. Two front-panel buttons let you toggle units, recall peak values, and set user-selectable threshold alerts for attention-grabbing warnings.

• 87% larger center LED display than earlier digital models for easier reading
• Sweeping edge LED acts like an analog needle for quick glances
• Programmable peak/recall and metric/standard options via two buttons
• User-settable thresholds trigger visual warnings when pressure crosses limits

How simple is installation and mounting in tight dash spaces?

The ZHSYMX gauge features a single-board design that keeps cup depth under 18.8 mm, allowing installation where thicker gauges won't fit. The compact form factor lets you mount the instrument on the dash, pillar pod, or console with minimal intrusion.

• 52mm (2-1/16") face size fits most standard gauge pods
• Shallow overall depth (under 18.8 mm) for flexible mounting options
• Works with common NPT 1/8" pressure ports and adapters
• Compatible with both 12V and 24V vehicle electrical systems

What maintenance and support should I expect?

The gauge is built for routine automotive use and requires no special upkeep beyond proper sensor installation and wiring. ZHSYMX provides customer support for product questions and troubleshooting to help with setup or operational concerns.

• Low-maintenance electronic design with durable components
• Replaceable pressure sensor if needed for serviceability
• Manufacturer support available for installation or performance questions
• Simple wiring harness and mounting hardware reduce installation time

Who this is for: The ZHSYMX 2-1/16" oil pressure gauge kit is aimed at vehicle owners, hobbyists, and professional technicians who want accurate, easy-to-read oil-pressure data without sacrificing dash space. It's a practical upgrade for anyone monitoring engine health on street cars, race vehicles, light trucks, or fleet equipment who needs a compact digital display, programmable alerts, and a straightforward fit into standard gauge locations.
