COGENG-Understanding These Pressure Sensors (Volvo, Danfoss )-VOE16213230 vs E311982 vs MBS 1250

Introduction

If you work with heavy equipment – excavators, wheel loaders, forestry machines, or hydraulic systems – you've likely encountered pressure sensors from Volvo, Danfoss, or the MBS 1250 series. These sensors are critical for monitoring hydraulic pressure, oil pressure, brake pressure, and more.

However, the part numbers and certifications can be confusing. Today we're clearing up the confusion around three specific identifiers:

VOE16213230 – a Volvo part number
E311982 – a UL certification number associated with Danfoss
MBS 1250 – a sensor series from Danfoss

The key insight: VOE16213230 and E311982 essentially refer to the same physical pressure sensor, with the difference being the part number system – one from Volvo, the other from Danfoss. Both fall under the broader MBS 1250 family, but there are design variations (square vs cylindrical) within that family.

In this comprehensive article, we'll cover:

What each part number/certification means
The relationship between VOE16213230, E311982, and MBS 1250
Square vs cylindrical design – which one do you need?
Certification and safety standards
Applications and compatibility
Buying considerations and logistics

What Is a Pressure Sensor and Why Does It Matter?

A pressure sensor (or pressure transmitter) converts hydraulic or pneumatic pressure into an electrical signal that the machine's ECU (Electronic Control Unit) can read. These signals are used for:

Hydraulic system monitoring – ensuring proper pressure for boom, arm, bucket, and swing functions
Brake pressure monitoring – critical for safety on wheel loaders and trucks
Oil and fuel pressure monitoring – protecting engines from low-pressure damage
Transmission pressure control – ensuring smooth gear shifts

When a pressure sensor fails, you may experience:

Error codes related to pressure readings
Hydraulic functions becoming slow or erratic
Engine derating or limp mode
Brake system warnings – unsafe for operation
Transmission shifting issues

Replacing a faulty pressure sensor with a high-quality equivalent is essential for safety, performance, and uptime.

Product Overview: Three Identifiers, One Core Product

1. VOE16213230 – Volvo Part Number

VOE16213230 is a Volvo construction equipment part number. It is used in:

Volvo excavators (e.g., EC series)
Volvo wheel loaders (e.g., L series)
Volvo articulated haulers

This part number refers to a specific pressure sensor used in Volvo hydraulic and brake systems. It is a direct OEM replacement for machines that originally used this number.

2. E311982 – Danfoss UL Certification Number

E311982 is NOT a product model number – it is a UL (Underwriters Laboratories) electrical safety certification number. This certification is held by Danfoss and applies to certain pressure sensors manufactured by Danfoss (or an OEM on their behalf) that meet UL safety standards.

Key points about E311982:

It is a certificate number, not a product series
It indicates the sensor has passed UL electrical safety testing (insulation, dielectric strength, flame resistance)
It is associated with Danfoss as the certificate holder
It has no direct link to the COGENG brand – COGENG manufactures sensors that are functionally and dimensionally identical to the Danfoss-certified sensors

3. MBS 1250 – Danfoss Sensor Series

MBS 1250 is a well-known sensor series from Danfoss. These are compact pressure transmitters designed for industrial and mobile hydraulic applications. Key features of the MBS 1250 series:

Rugged stainless steel construction – suitable for harsh environments
High overpressure capability – withstands pressure spikes
Temperature-compensated – accurate readings across a wide temperature range
Multiple pressure ranges – from 0–10 bar up to 0–600 bar
Various output signals – typically 4–20 mA, 0–10 V, or ratiometric

The MBS 1250 series includes different physical designs – and this is where the square vs cylindrical difference comes in.

Square vs Cylindrical – What's the Difference?

Within the MBS 1250 family, there are two common physical designs:

Square/Block Design (Rectangular Housing)

Typically features a rectangular or block-shaped housing with a built-in electrical connector (often Deutsch or AMP style)
Commonly used in mobile hydraulic applications on excavators, loaders, and tractors
Often has a higher ingress protection rating (IP67 or IP69K)
The connector is usually integrated into the body – no flying leads

Cylindrical Design (Round/Tube Housing)

Features a cylindrical or tube-shaped housing – similar to a small cartridge
Often has a cable output (flying leads) or a smaller threaded connector
Commonly used in industrial, pneumatic, or lighter-duty hydraulic applications
May have a smaller footprint for tight spaces

Which One Do I Need?

The choice depends on your machine and the original sensor design:

If your original Volvo part number is VOE16213230, you typically need the square/block design with a Deutsch or AMP connector.
If your original Danfoss sensor has a cylindrical body with a cable, you need the cylindrical version.
Always check the physical connector type, mounting thread size, and pressure range.

Important: Both square and cylindrical designs can carry the E311982 UL certification – the certification applies to the electrical design, not the physical housing shape.

The Relationship: VOE16213230, E311982, and MBS 1250

Here's the simplified relationship:

Identifier	Type	Description
VOE16213230	Volvo Part Number	The OEM part number used by Volvo for this pressure sensor
E311982	UL Certification Number	The safety certification held by Danfoss for the sensor design
MBS 1250	Danfoss Product Series	The sensor family that includes both square and cylindrical designs

The bottom line:

VOE16213230 is a specific Volvo part number that refers to a pressure sensor in the MBS 1250 family.
That sensor carries the E311982 UL certification because it is manufactured to Danfoss standards.
COGENG manufactures replacement sensors that are functionally and dimensionally identical to the Volvo/Danfoss products, matching both the VOE16213230 part number and the MBS 1250 specifications, with the same safety and performance characteristics.

In other words: VOE16213230 ≈ E311982-certified MBS 1250 sensor – same product, different naming convention.
