The Hydraforce TS38-20A-0-N-12ER (5122328) is a high-accuracy, heavy-duty pressure sensor designed for demanding industrial and off-highway equipment applications. It achieves a 1% total error band accuracy by integrating advanced ASIC technology with a stable, field-proven polysilicon thin-film pressure sensor. This sensor operates efficiently within a temperature range of -20 to 85\u00b0C (-4 to 185\u00b0F), providing reliability and accuracy in various environmental conditions. With features like reverse polarity and miswire protection, broad temperature capability, all-welded pressure construction, and a high EMI/RFI rating, it is built for durability and resilience. The IP67 ingress rating ensures protection against dust and water ingress. Additionally, the TS38-20A-0-N-12ER functions as a direct-acting, single-stage, poppet-type proportional pressure-relieving valve. The regulated pressure is proportional to the input electrical current; when no current is applied, the valve allows free flow from port 1 to port 2. It supports an industry-common cavity with an optional manual override feature. The valve has a pressure rating of 248.2 bar (3600 psi), proof pressure of 268.9 bar (3900 psi), and burst pressure of 751.5 bar (10900 psi). It offers adjustable pressure ranges up to 206.8 bar (3000 psi) depending on configuration. The flow rating is set at 11.4 lpm (3 gpm) from port 1 to port 2 when the coil is de-energized, with maximum internal leakage of 1 ml/min at specified conditions. Temperature ratings vary based on seal material, with operating fluid temperatures ranging from -40 to 204 \u00b0C (-40 to 400 \u00b0F). The unit weighs approximately 0.18 kg (0.39 lb) and requires specific installation torques for both cartridge installation and coil nut torque, ensuring proper setup for optimal performance in hydraulic systems using mineral-based or synthetic fluids within specified viscosity ranges.
