Selecting a pressure sensor involves more than simply matching specifications. Engineers must balance performance, reliability, packaging flexibility, and long-term availability. While many customers first discover the AV Sensors CHT-1230 Series as a drop-in replacement for the TE 1230, that perspective only captures part of the product's value.
The CHT-1230 is a modern pressure sensor platform designed to support both existing equipment upgrades and entirely new OEM developments. By combining Ceramic Hybrid Technology, high accuracy, and flexible packaging options, the CHT-1230 provides engineers with a versatile solution for a broad range of applications.
Supporting Existing Designs Without Costly Redesigns
For OEMs with products built around the TE 1230 footprint, the CHT-1230 offers a practical migration path. Mechanical compatibility, familiar electrical architecture, and multiple pneumatic port options help manufacturers reduce redesign costs, minimize qualification effort, and maintain continuity within existing product families.
Rather than investing engineering resources in board redesigns, software validation, and recertification activities, manufacturers can focus on supporting their installed customer base while maintaining production continuity.
For many organizations, this compatibility is a valuable advantage. However, it is only one reason to consider the CHT-1230.
Designed for Performance
The CHT-1230 utilizes Advanced Sensor Ceramic Hybrid Technology to deliver performance characteristics required by today's demanding applications.
Key benefits include:
High accuracy
Low thermal errors
Wide temperature compensation
Excellent long-term stability
Fast response time
Low output noise
The sensor is temperature compensated from -20°C to +70°C and provides typical pressure non-linearity of only ±0.10% full-scale span. Combined with its rugged ceramic substrate construction, these characteristics help ensure stable performance across a wide operating range.
Whether used in a medical device, industrial controller, or environmental monitoring system, the CHT-1230 is engineered to deliver reliable measurements over the life of the product.
Flexibility for New Product Development
While replacement opportunities are important, many customers select the CHT-1230 for completely new designs.
The platform supports:
Absolute, gauge, and differential pressure measurement
Pressure ranges from 1 PSI through 300 PSI
Multiple port configurations
Pins-up or pins-down mounting options
Compact dual in-line packaging
This flexibility allows engineers to optimize both pneumatic and PCB layouts while maintaining a common sensor platform across multiple products.
For companies developing families of instruments, the ability to standardize on a single pressure sensor architecture can simplify purchasing, manufacturing, and long-term support.
Field Interchangeability Simplifies Manufacturing
A unique feature of the CHT-1230 is its support for field interchangeability through the integrated gain-set resistor architecture.
When implemented according to the recommended application circuit, sensors can be replaced without extensive recalibration procedures. This capability can help OEMs simplify manufacturing, reduce service complexity, and lower maintenance costs throughout the product lifecycle.
For manufacturers producing equipment over many years, this benefit can translate directly into operational savings.
More Than a Replacement
While many engineers initially evaluate the CHT-1230 as a TE 1230 replacement, they often discover that its greatest value lies in its overall performance and versatility.
The combination of high accuracy, low thermal errors, field interchangeability, and long-term product availability makes the CHT-1230 a compelling choice for both legacy equipment support and next-generation product development.
Whether replacing an existing sensor or designing a new system from the ground up, the AV Sensors CHT-1230 Series provides a proven pressure sensing platform built to support today's requirements and tomorrow's opportunities.
