I. Core Specifications

1. Pressure Range

Operating Pressure: 5–150 psi (0.35–10.30 bar)

Proportional / Differential Pressure Range: 5–23 psi (0.35–1.60 bar)

Maximum Sustained Pressure: 15.5 bar (225 psi)

2. Electrical & Output

Output: Single potentiometer, 140 Ω (outputs a variable resistance signal in response to pressure changes)

Rated Voltage: 24 VAC

3. Mechanical & Environmental

Sensing Element: Brass bellows

Connection: 1/4" NPT female thread

Temperature: 0–66 ℃ (32–150 ℉)

Dimensions: 146 × 114 × 70 mm; Weight: approx. 1.5 kg

Mounting: Wall mount (backplate fixed)

II. Operating Principle

The pressure medium enters the bellows, undergoing a pressure-to-displacement conversion;

This displacement drives the slider of the 140 Ω potentiometer, generating a resistance signal proportional to the pressure;

The controller panel allows for the setting of both the operating pressure and the proportional bandwidth, enabling continuous and smooth pressure modulation (non-switching type).

III. Typical Applications

Proportional control of boiler steam pressure;

Air pressure / airflow modulation in HVAC systems (fans, dampers, compressors);

Closed-loop pressure control for non-corrosive gases/liquids in industrial processes.

IV. Model Variations (L91 Series)

L91A: Single potentiometer, fixed proportional bandwidth;

L91B: Single potentiometer, adjustable proportional bandwidth (this model);

L91D: Dual potentiometers, synchronous motor drive, adjustable proportional bandwidth.
