The Keller Preciseline high accuracy pressure transmitter combines piezoresistive silicon sensor technology with Keller's state-of-the-art signal conditioning circuitry to make a very reliable transmitter with excellent Total Error Band (TEB) accuracy over a wide compensated temperature range.

The ability of the Preciseline to provide this level of sustained performance over a wide range of operating conditions makes it ideally suited to pressure monitoring applications such as tank level measurement, pump control, and VFD control.

The Preciseline transmitter with PE jacket is approved to NSF 61 and NSF 372 standards for water quality. The most recent model, the Preciseline SDI transmitter, is the serial digital interface version. It combines two industry standard digital communication protocols (SDI-12 & RS485), making it ideally suited for environmental monitoring bubbler applications such as surface water, streams, and reservoirs using existing SDI-12 monitoring equipment.

Here's how some of our customers use this product...

Performance Testing Undersea Remotely Operated Vehicles

The Background: The customer manufactures work-class remotely operated vehicles (ROVs) and manipulator arms used primarily in the undersea oil and gas industry. They are developing a new product and require pressure sensors in order to characterize its performance (power vs performance, low speed performance, precision control).

The Problem: This testing exposed the pressure sensors to undersea conditions as well as hydraulic fluid and high pressures/flow associated with monitoring the hydraulic systems that control the ROV functions.

The Solution: The customer purchased Keller Preciseline high accuracy pressure transmitters based on their cost, quality, and performance. They have an IP68 rating making them ideal for underwater conditions and are available with the accuracy and pressure ranges needed for this application. Additionally, they integrated seamlessly with the customer’s existing data collection instruments.
